Hope this comes in handy for you all - the main problems are likely to be: they don't render if you don't use a font that supports these characters (as they are separate unicode characters) - and also when your fonts are small they will probably render far too small, which is obviously a problem too!

To add a bit of detail re Space Cadet Pinball: we built Space Cadet originally at my company Cinematronics and did a deal with Microsoft to ship it with the Plus Pack that accompanied Win 95 and Win 98. While it technically didn't ship w/ Windows, the Plus Pack had something like a 25% attach rate and pinball wound up on most systems anyway. Microsoft actually had an option in our original contract from 1994 to ship it with the OS itself or the Plus Pack. Maxis was our publisher for the subsequent retail version, and later bought my company. More germane to this thread: I believe Dave's port entered the picture a few years later, after Win 98, and was likely critical to pinball continuing to ship on later iterations of the Windows OS (i.e. 32-bit). I definitely appreciate the time he put in to give the game extra years of life on the Windows platform. Kevin Gliner, game designer and producer for 3D Pinball, and co-foun

Context

As AutoShare text processing doesn't work on my device, I spent the last few days designing a text processor that would work without it (and even more, without any plugins!)

It currently supports 5 text processors: LaTeX, superscript, subscript, uppercase and alternated case. And you can of course implement your own processors. You can see it here: https://youtu.be/CZWPYGiwc-Q.

I've been inspired for some aspects by FloatingOrange's project. But two things were bothering me in the project: dependency on AutoTools and AutoInput, and usage of clipboard to process the text. I wanted to get something working in native Tasker, and which doesn't use the clipboard as I feel like it's more a workaround than a real solution.

How to use it

The easier way to process text is to assign the main task to a quick tile. The task TP_setup_initializeProject sets up the second Tasker quick tile (and initializes some variables). You can also link it to any shortcut you usually use (I personally use it with the app Swiftly Switch to launch it from the edge of my screen).

If text is selected, only the selected part will be processed. If no text is selected, the whole text in the text field will be processed. If you aren't in a text field, the processing will be aborted.

When you perform the main task, it will propose to you a list of available processors. Those are the tasks beginning with TP_processor_. Once you've selected the processor, the text is processed and replaced, using keyboard actions, that's it!

At the end, the cursor tries to move to where it was initially. Unfortunately, it will probably be misplaced if the chosen processor modify the text length.

Implemented processors

1. LaTeX-like converter

That one was the main part of my project. As a mathematics student, I often have to discuss formulas with friends by text, and it is waaay easier to read √(β₁+eⁱᶿ) than something like sqrt(beta1+e^(i*theta)).

I know that a lot of mathematical characters exist in Unicode. Some keyboard allows us to use them, but having to change keyboard each time you need a symbol can be quite annoying... That's why I wanted to implement some LaTeX-like replacement in my text. For example, processing the text \sqrt(\beta_1+e^{i\theta}) will result in the above example. I tried to stick as much as I could to LaTeX syntax.

Sym

A while ago, I decided to develop a mathematical notation for personal purposes that would satisfy the following needs:

1. Quickly and easily usable from a computer
2. Expressing information in a compact way
3. The ability to fully use the Unicode character set, no shame in stealing symbols from other cultures
4. Eliminating ambiguities by assigning a unique name to a single concept; in this context uniqueness simply refers to the way a name looks, not what it means. Function overloading is still allowed as long as the function variants make sense

And thus I've developed quite a catalogue of notations that I use mostly for personal use (no, I don't use them when I take formal exams Jimmy, no go back to r/math and look at what n0rmies post). In this first volume I'll show some of the most simple ones.

Given a list of two real numbers L, the difference between the second and the first is denoted like this:

引算(L) ≔ L[2] - L[1]

"引算" (read as "hikizan") means difference or subtraction in Japanese. If you ever need to do the difference between the first one and the second one, you can just use the following variant:

引算^(⚹)(L) ≔ - 引算(L) = L[1] - L[2]

That little thing as a superscript is the character "sextile" ⚹, (Unicode = +26B9 ). This difference operator can be easily used in other cases as long as the two quantities support the subtraction operation.

The next one is the fraction operator. Given a list L of two real numbers, the fraction operator represents the ratio of the first divided by the second:

分数(L) ≔ L[1] / L[2]

分数^(⚹)(L) ≔ L[2] / L[1]

"分数" (read as "bunsuu") means literally fraction in Japanese; this notation can be used also with complex numbers, though in that case you should put a "z" at the subscript. When L[1] is equal to 1 though, you can use the handy shortcut:

⅟( x ) ≔ 分数( 1, x )

Also if you have a vector that's being divided by a scalar, you can also use this notation as well; however, the second argument can never be a vector (unless you use the sextile variant, in that case the first argument can never be a vector).

That's it for this volume, see you in Volume 2 for more notations and crazy function names !

Item Number: SCP-0001

The Solution

Object Class: Thaumiel/Apollyon

If the object class didn’t make it apparent enough, this is about to get really, really weird.

Jack Ike’s works can be incredibly complex, intuitive, and sometimes can get a bit too carried away. However, a Jack Ike 0001 proposal is not only all of those things, but more. A number of prolific authors have downvoted the piece (as well as upvoted), which is understandable — it took me over seven reads of this article to even get an idea what was going on. But now, as I write this, I think I finally understand enough to convey just how well-nuanced this SCP is, and why it should stay on the mainsite.

If you don’t want to go through the entire article and extrapolate it alongside me, there will be a TL;DR at the end for you to get a quick runthrough of it.

So, my fellow scholars, electrocute the bubbling mass of stars, enlighten a crab with toothbrushes, but notwithstanding the quadrupeds, and let’s get right into it!

I think the best way we can introduce this article is by displaying the introduction to the article itself:

> Item #: SCP-0001 > > Object Class: Thaumiel/Apollyon > > Special Containment Procedures: SCP-0001 cannot and should not be contained by the Foundation.

What a start, huh? Let’s dissect this.

The Item Number is SCP-0001. Pretty standard for an SCP-001 proposal, except for the fact that it has three zeros instead of two. This gives us an idea that this is happening in a later point of the Foundation canon, as there are four digits instead of three.

The object class is not only Thaumiel, but also Apollyon. For those unacquainted, Thaumiel means that an object is beneficial to the Foundation and counteracts the effects of other dangerous anomalies; Apollyon being an object which cannot be contained and will destroy everything. How can this object be both at once?

The Special Containment Procedures seem to align with the object class. It can’t be contained, but it shouldn’t be contained, either.

Onto the description, which is surprisingly short.

We’re introduced to three objects: SCP-0001 itself, SCP-0001-Α (Alpha), and SCP-0001-Ω (Omega), though we only get details of SCP-0001 now. SCP-0001 is described as a “autonomous biomechanical device produced by SCP-0001-Α and SCP-0001-Ω during Project Phantasos,” meaning it’s a machine with organic and met

Šulmu!

As a first post here, I would like to introduce my modus operandi for using the ancient Middle Eastern scripts in the modern world. Please feel free to contribute!

• For Ancient Egyptian, Hebrew and Arabic are both related. I generally use Hebrew as it is closer chronologically speaking to hieroglyphs.
• For cuneiform, as it is a language isolate I generally employ the ancient script (which has a Unicode block) but failing this I use English with superscript to indicate determinatives.📝
• For Canaanite, I like to use Arabic. Although Hebrew is chronologically closer I enjoy the aesthetic value of Arabic and how it distinguishes from Æ.

📝 “...reddit does support the use of cuneiform characters, e.g. 𒀊. While I don't enforce any standards for transcription or transliteration on our board, I try to be consistent with how I present cuneiform. Here are the standards that I've found to be useful:

• ⁠The name of a cuneiform sign, when transcribed into English, is presented in capital letters, e.g. 𒀊 is the AB-sign, simply called AB • ⁠The names of a string of cuneiform signs, when transcribed into English, are separated by periods, e.g. 𒀊𒁀 is transcribed AB.BA • ⁠The values of a cuneiform sign, when transliterated into English, are written in lowercase letters. Optionally, these can be enclosed within two forward slashes for better visibility, e.g. 𒀊 has the values /ab/, /aba/, /ap/, /eš3/, /iri12/, and /is3/ • ⁠When transliterating a string of cuneiform sign values, separate each with a hyphen. Optionally, enclose the whole construct within two forward slashes for better visibility, e.g. 𒊩𒌆𒀭𒀝 is transliterated /nin-an-ak/ • ⁠When transliterating, determinative-signs are represented using the superscript format. Optionally, capitalize the sign name in question, put a single space between it and any other signs, and enclose the entire construct between two forward slashes for better visibility, e.g. 𒀭𒈹 would be transliterated /D inana/, and 𒉣𒆠 would be transliterated /eridug KI/ • ⁠In order to distinguish between homographic sign-names and homophonous sign-values, transliterators makes use of subscript numerals, but since Reddit doesn't support the use of subscripts, I also identify these with superscript formatting, e.g. 𒀊 is the AB-sign while 𒀖 is the AB2-sign; and 𒁳 has the value /dab/, 𒋰 has the value /dab2/, 𒁾 has the value /dab4/, 𒆪 has the value /dab5/, and 𒍏 has the value /dab6/ • ⁠When normalized, Sumerian language words a

I am developing a very professional typeface. Every single font of the typeface will contain at least 10445 Unicode characters, but also 1193 superscripts, 1193 subscripts, 362 superscript superscripts, 362 superscript subscripts, 362 subscript superscripts and 362 subscript subscripts. I know exactly how to design those characters, but how would I assign superscript superscripts, superscript subscripts, subscript superscripts and subscript subscripts to an OpenType feature?

I've started making free tools to write chemical formulas and do simple calculations - this is the first prototype.

It is not designed for mobile browsers.

http://shout.education/elements/E001/E001.html

Currently, you can:

• 'Type' the chemical formula using a responsive periodic table with options for many common isotopes
• Use a mini-keyboard for the chemical formula
• Automatically get the empirical formula and formula mass
• Edit and clear the chemical formula
• Copy outputs to the clipboard

There are a lot of things I want to improve: I'd really like some feedback on the key functionality.

Formulas use Unicode characters, so you don't need to worry about how the program you copy them into handles superscripts or subscripts.

Roots in my document don't get stretched properly whenever the root index is specified through \sqrt[index]{}

http://puu.sh/BM01B/28f67903aa.png

\begin{align}
    x &= \ldots\notag\\
    y &= \sqrt[n]{
                2\sum_{k=1}^{n\,/\,2}% n / 2
                \binom{n}{2k-1}\, p^{n\kern.1em(n- \kern.1em 2k \kern.1em+1)} q^{n\kern.1em(2k-1)}
            }\notag\\
    z &= \ldots
        \label{eq1}
\end{align}

It seems that the issue is present regardless of the content of the root, or the type of environment the equations are written in.

https://puu.sh/BM1Fe/9634bc3ff1.png

\begin{equation*}
  \sqrt{\sum e^x}
    \quad
  \sqrt[3]{\sum e^x}
    \quad
  \sqrt[\leftroot{-2}n]{\vphantom{\sum}\sum e^x}
    \quad
  \sqrt{2^{\sqrt{2}}}
    \quad
  \sqrt[n]{2^{\sqrt{2}}}
    \quad
  \sqrt{\int_{k}^{\infty} \frac{x}{y}}
    \quad
  \sqrt[n]{\int_{k}^{\infty} \frac{x}{y}}
    \quad
  \sqrt{9}
    \quad
  \sqrt[3]{9}
\end{equation*}

Can't determine what is causing this.

The equations are enclosed in standard environments within running text under \subsection*{}. I haven't redefined the root command or the equation / align environments. Perhaps my math font is causing this? I'm using xits font which is supported by both fontspec and unicode-math.

I'm using fontspec with [no-math] for body text font and unicode-math for the math font and this is the only issue i have with equations rendering.

\usepackage[math-style=TeX, bold-style=TeX, nabla=upright, partial=upright]{unicode-math}
  \setmathfont{xits-math}
  \setmathfont{xits-mathbold.otf}[range={bfup->up, bfit->it}]

\DeclareMathSizes{9}{9}{7.65}{7}

Should I attach how my math packages are loaded too?

Would like to avoid using \left(equation\right)^{\frac{1}{n}} as that would look and read bad with all the superscripts and subscripts.

Hey, I've been playing Pokémon GO for only a week and I already can't do without CalcyIV, I'm really loving the app!

#Suggestions: I've two suggestions that I would like to see implemented regarding the renaming system:

• 1. A NameX building block that fills any remaining character spaces with the monster name. With an option to configure the length of the complete name.
• 2. An IV% Range format option that puts the minimum range value as subscript and the maximum range value as superscript, without a divider character in between.

#Examples: Using the building blocks NameX``IV% Range``A-MoveABC``D-MoveABC``MoveTypeswith the length configured to 12, it would give the follow results:

Nid♂₅₈⁶⁴AB☁○

Nidor♂⁸⁸AB☁○

Nidora♂⁸⁸AB☁

Sand₈₂⁸⁹AA⚓❄

NOTE: I know some of the provided naming examples are not usable in the game, see "Other findings / thoughts" below.

Maybe even add a slider (or adjust buttons) to configure the length on the fly on the output window. Or maybe it's possible to fill multiple clipboards which then allows any keyboard app to paste the correct one, but this might be a stretch :p (for situations the game doesn't accept the provided name)

#Question: I don't see a difference between the IV% Range format 50 and 0,...,99 or is that because it's limited to 99 and thus ignores perfect IVs?

#Other findings / thoughts: NOTE: See "Update" below

After testing renaming a monster using different characters like subscript, superscript and any other unicode characters (such as icons); actually decreases the amount of characters you can use. It will give the "Please enter a different nickname" message, so the suggestion from above might not be the best. For example: Sa₈₂-₈₉AA⚓❄ is not allowed but Sa82-89AA⚓❄ is, and that is only 11 characters, removing ⚓❄ and replacing them with +* allows you to use an extra character making San82-89AA+* possible which uses the full 12 characters. If you want to use the MoveTypes building block it would mean that you need to configure the building block NameX length to 11 to prevent any errors. I suppose after enough testing the length can be automatically calculated based on what building blocks are used.

I'm looking for a solution that is clear and uses the least amount of characters, specifically for IV% Range. Maybe the following format might be useful: 80+9 to describe a range of 80 to 89 (saves one character if the difference is below 10).

#Update: After te

I have an equation that I want to use as a title in the game Osu, which only accepts unicode AFAIK. Is there a way I can convert something with subscripts and superscripts to something similar in unicode?

\Delta M_i^{-1} = -\alpha\sum_{N}^{n=1}D_i[\eta][\sum_{j\in C[i]}F_{ji}[\eta - 1]+Fext_i[\eta^{-1}]]

The latex on codecogs editor

As it's often necessary on this subreddit to format mathematical expressions in reddit, the following is a brief overview for those unfamiliar with how the reddit formatting system works with respect to things like exponents and asterisks, in addition to providing some lesser-known unicode characters.

If you have 5-10 minutes, take a little time to read the official reddit guide and this user-created introduction. If you've picked up what you know from browsing and occasionally clicking "source", you will likely be unaware of many of these things.

If you don't have the time, here's a quick intro on mathematics formatting:

Asterisks

*text* gives text.

This means that if you type "3*5 is 15 and 4*2 is 8", you'll get "35 is 15 and 42 is 8." Notice how the asterisks disappeared, and the text in between became italicized! To avoid this, use a backslash (the \ thing) before the asterisk by typing "3\*5 is 15 and 4\*2 is 8".

Superscripts

This is very similar; using a ^ character will create nested superscripts. For example, typing 2^2^2 gives 2^(2^2). However, maybe you want to have 5^(5)+1, so you type 5^5+1 and it gives you 5^(5+1). That's not what you wanted!

This is because reddit doesn't know when you want your superscript to end, so it will normally stop when it encounters a space. This means that you can avoid this by typing 5^5 +1, but that will leave an awkward gap in your text. The best way to fix this is to use parentheses, and type 5^(5)+1. Reddit will then raise only the 5 and keep the rest as normal text, producing 5^(5)+1.

For the advanced reader: Sometimes, if you're trying to type out a complicated expression where you want to have parentheses in there, reddit will get a little confused and won't deal with your spaces very well. When this happens, you'll want to use the text ( to create the ( symbol and ) to create ). For example: Say you want to write e^(x(x+1))y^(2).

You might type e^(x\(x+1\))y^(2), which you'd expect to work. But then reddit produces e^(x(x+1))y^(2), bringing your parenthesis down before you wanted. To fix this, type e^(x(x+1))y^(2), which will make what you want (notice how where the parentheses used to be has been replaced by that ( stuff).

In addition, you can use

Try this:

"5$tc(utf, 2072)$ = 25" "H$tc(utf, 2082)$O"

More utf code here: http://www.fileformat.info/info/unicode/block/superscripts_and_subscripts/list.htm

1. Please consider auto-linking subreddit addresses. Anything that matches /r/something should link to that subreddit. Yes, even if it doesn't exist... I'd be ok for those to 404 or whatever.
2. You have the /r/blog subreddit. Use it as the blog. Yes, you've said over and over that you need images... markdown supports this. Turn it on only for admins... we're ok with it. It's your fucking site, you really are allowed to do that, especially when it's for a non-trite reason. Be proud of your software for once, and get rid of that awful Blogger/Wordpress/whatever-the-fuck it is.
3. Please PLEASE please modify markdown just a little bit. We need subscripts and superscripts... some of us have things to say that require these. Strikethrough would be nice, but it's harder to make a case for that, other than that the FTFY inanity would be a little nicer looking (assuming those mouth-breathers could be bothered to use it).
4. Some cross-posting would make sense. It's bad when someone wants to ask a question and needs to post it both places, and gets two different sets of answers. Some stories are both worldnews and politics, some things are both frugal and cooking. They wouldn't literally have to be the same story internally in the database... keep them separate so each group of moderators can sink it in their respective subreddits if needed, but that the others can still see it.
5. As above, please consider some merge functionality. Something only you admins can use, but that would allow you to clean up the front page a little. Both sets of comments would appear in one place, and however you reconcile which link/headline to use... that's fine by me. If it only gets used a few times a year, it'd be great. When it's needed, it's really needed.
6. An automatic subreddit for everyone, with the same name as their username. You'd need to put it under another namespace... maybe /b/ketralnis or something like that. Automatic crossposting any submissions to this would be nice.
7. Loosen up on the username limits. Maybe spaces, but definitely more than 20 characters. And for those of us not in the US, allow some unicode for crying out loud.

I'm thinking of building a small keypad (a modified separate numpad) that has all the commonly used greek symbols, as well as things like angstrom, and subscript/superscript modifiers. Would anyone use this? Does this seem like a useful piece of kit? A quick google search brings up no hits. If anyone has heard of this please link it, because I would buy it. Yes I know some keyboards have macro keys but all the ones i have used have been very slow, and would not have enough keys to cater to all the chemistry symbols. A modified keyboard hardware set-up would be instant and would have plenty of keys. This is so much faster than going into microsoft words/openoffice symbol input or remembering and using the correct unicode in latex. Thoughts?

I've been working on finding a way of adding notes to PDF powerpoint handouts. I've tried a few options such as Evernote and Notability and they're alright, but nothing seems to offer the option of actually having control over font, size, superscript/subscript, etc.

I'm currently using Evernote as it's convenient but the lack of control is very frustrating.

I'd really like to find a notetaking app that actually provides decent typographic control for annotations or text overlay.

I've been considering using something like Word or Pages (on OS X) and finding a way to add a multi page background. Once that was in place I could just set an indent so that the text would all sit down the right side of the page.

The only downside would be that I'd have to find a way to remove/mask the lines that powerpoint puts in for handouts.

I'm primarily working in OS X and iOS but could be convinced to try something else if it's the only option.

Edit: solution for sub/superscript - Unicode offers most of the needed characters so by using the text expansion feature through system prefs I have added shortcuts that parse something like &&2 into a subscript 2. Not ideal, but it works. Still no font control but I can type chemical reactions without them looking silly.

I wrote up an introduction on formatting math expressions on reddit for /r/mathriddles, and I've seen some of the same issues come up for redditors on /r/math. If anyone's interested, here's an overview of reddit formatting with the specific goal of writing math expressions.

If you have 5-10 minutes, take a little time to read the official reddit guide and this user-created introduction. If you've picked up what you know from browsing and occasionally clicking "source", you will likely be unaware of many of these things.

Either way, here's a quick intro on mathematics formatting (much of which won't be found in the above links):

Asterisks

*text* gives text.

This means that if you type "3*5 is 15 and 4*2 is 8", you'll get "35 is 15 and 42 is 8." Notice how the asterisks disappeared, and the text in between became italicized! To avoid this, use a backslash (the \ thing) before the asterisk by typing "3\*5 is 15 and 4\*2 is 8".

Superscripts

This is very similar; using a ^ character will create nested superscripts. For example, typing 2^2^2 gives 2^(2^2). However, maybe you want to have 5^(5)+1, so you type 5^5+1 and it gives you 5^(5+1). That's not what you wanted!

This is because reddit doesn't know when you want your superscript to end, so it will normally stop when it encounters a space. This means that you can avoid this by typing 5^5 +1, but that will leave an awkward gap in your text. The best way to fix this is to use parentheses, and type 5^(5)+1. Reddit will then raise only the 5 and keep the rest as normal text, producing 5^(5)+1.

For the advanced reader: Sometimes, if you're trying to type out a complicated expression where you want to have parentheses in there, reddit will get a little confused and won't deal with your spaces very well. When this happens, you'll want to use the text ( to create the ( symbol and ) to create ). For example: Say you want to write e^(x(x+1))y^(2).

You might type e^(x\(x+1\))y^(2), which you'd expect to work. But then reddit produces e^(x(x+1))y^(2), bringing your parenthesis down before you wanted. To fix this, type e^(x(x+1))y^(2), which will make what you want (notice how where the par
