Notes on monospace, fonts, ascii, unicode

WEB a

INSPIRATION FOR THIS SITE

stonegray.ca (archived), before redesign
Uses :before and :after CSS elements to decorate elements like [ tag ]. Also uses <-- as a navigation element
www.rfc-editor.org/rfc/rfc1034.html
RFCs are nostalgic and info dense; hard line-wrapped at 80ch. Sometimes they have cool diagrams
kary.us/nota
The cleanest box drawing I've seen. Unicode heavy. Custom font
plaintextsports.com
Plaintext UI. Cool formatting ideas, thin centered content column, fetches data too. See also game graphs like this one. Probs unfriendly to screen readers tho (but heck, so is this page)
computer.rip
True plaintext content. Uses 4ch blockquote margins and bold and >>> for formatting
berkeleygraphics.com/typefaces/berkeley-mono/#doc-tab-1
Attractive box drawing mockups
mcj.sourceforge.net/fig-format.html
Help text example with elements like parenthesized enumerations (3.4) and double asterisks ** and tab-style column alignment. But not mobile friendly, just baked whitespace at 80ch like RFCs
wttr.in
Unicode and ASCII that work together; good use of color and graphics; plaintext and curl and other data support (not just HTML)
garden.bradwoods.io
Monospaced font mixed with minimal box borders. Uses SVG instead of ┗━ for inline file tree. Sort of a div soup tho
xeiaso.net/blog (archived), before redesign
Blockquote in footer achieves a vertical line of >'s with CSS :after, content ">\A>\A>\A...", white-space pre, and absolute positioning
fabiensanglard.net
Plaintext content. Minimal styling with bold / underline. Uses dejavu sans mono and floated inline graphics
7guis.bradwoods.io
Vanilla, structured HTML
cmpxchg8b.com/#articles
Boring HTML in a good way, and heavy on dashed borders. Pale bg color for inline code
hoverbear.org/blog/rust-state-machine-pattern
Full-width code blocks break out of content column (gain a few chars of max width on mobile)
what.happens.when.computer
I like the navbar: / index ^ archive # tags @ about

TIL

Some victims of broken box-drawing characters, at least when viewed on certain devices (scroll down the pages until you see box borders like ┌──┐): one, two, three

Apparently my phone's system monospace font doesn't support box drawing characters very well (Android, Roboto Mono). And apparently this is not just a mobile thing (Debian, Bitstream Vera Mono).

This website uses a font that includes box drawing characters so that the browser doesn't have to fallback to the system font. I doubt that these system fonts will fix their box drawing characters any time soon. Some fonts that seem to include their own box drawing characters: Commit Mono, Monofur, ...
Website domains can have emoji / unicode in them. Punycode is the algorithm that converts the unicode to ascii, since domains are supposed to be in ascii.
Eg. https://💩.la becomes https://xn--ls8h.la
Some websites put ASCII art in a /humans.txt file, as an easter egg: for example, netflix, disqus, html5rocks, and adultswim

Examples of ascii diagrams in code comments https://blog.regehr.org/archives/1653
Muhammad maintains a list of text2diagram tools: https://xosh.org/text-to-diagram/

A venn diagram using hexagons, proportioned for holding text, since circles are hard:

      _________________
     /                 \
    /                   \
   /            _________\_______

 /            /            \      \
 \           /             /       \

    \      \            /            /
     \______\__________/            /
             \                     /
              \                   /
               \_________________/

Note that the ideal hexagon aspect ratio depends on the font aspect ratio. These are 27x11 hexagons. With a wider font like Source Code Pro, 30x13 hexagons look better.

GAMES

Card games in the terminal, with cool playing card designs: csol
stone story rpg. the dev also gave a talk about ascii art techniques (video):
- created a custom font to get his preferred aspect ratio of 16:29, as well as ensuring pixel perfection at different font sizes
- extended ASCII with characters like latin accent ´ to complement backtick `, and likewise upside down exclamation mark ¡ to complement !
- developed anti-aliasing tricks to deal with angled and curved lines
- used dithering
Snake, 2048, and freecell games over SSH, with color and global highscores: ssh play@ascii.town

TERMINAL EMULATORS a

80 cols x 25 rows: the most common terminal screen size, dating back to teletypes and punch cards
About legacy font aspect ratios, from CRT days: https://16colo.rs/ansiflags.php
More on aspect ratios: Block chars (█) look best with wider fonts that have an aspect ratio close to 1:2. Eg. the super-skinny Iosevka font with ratio 1:4 will have super skinny distorted block-art output.
There's thin and thick versions of each box drawing char:
```
 ┌───┬───┐   ┏━━━┳━━━┓
 │   │   │   ┃   ┃   ┃  
 ├───┼───┤   ┣━━━╋━━━┫
 │   │   │   ┃   ┃   ┃   
 └───┴───┘   ┗━━━┻━━━┛
            
 light       heavy
```
They're sprinkled throughout U+2500 to U+257F. Be careful not to mix the light ones with the heavy ones - especially if your terminal emulator does a bad job of overriding the glyphs. See also alacritty's builtin_box_drawing config option. And the discussion in the Windows Terminal repo.
tput cols; tput lines: print terminal screen size
tput cvvis or tput civis: show or hide cursor (very visible versus invisible). See also tput cnorm

Some cool things to telnet into:
- Watch starwars with telnet towel.blinkenlights.nl, or watch the web port at asciimation.co.nz
- Zoom and pan around a world map with telnet mapscii.me
- Watch a globe move across the screen with tput civis; curl -s http://artscene.textfiles.com/vt100/movglobe.vt | pv -q -L 9600
On creating terminal emulators, and the associated challenges:
- Stress tests to evaluate rendering accuracy and performance: fire animation, Sonic ANSI art, UTF-8 torture test, UTF-8 sampler of different languages (which is more of a webpage stress test)
- An overview of weird character widths that terminal eumulators must support
- Mitchell Hashimoto mentions some IO throughput optimizations for the Ghostty terminal, among other great devlogs
on building TUI widgets: https://textual.textualize.io/blog/ and https://www.textualize.io/blog/7-things-ive-learned-building-a-modern-tui-framework/
what makes a great TUI? i have a whole blog post planned! so many good terminal applications out there these days. stay tuned

UNICODE a

About the pains of creating text systems: Text rendering hates you, and Text editing hates you too
String gotchas when working with non-ascii (examples from source 1, source 2):
- "🤦🏼‍♂️".length == 7
  Naive string length functions do not measure the number of glyphs rendered to the screen.
  
  Example: 🤦🏼‍♂️ is composed of a facepalm emoji, a skin color, a zero width joiner, a male symbol, and a variation selector. This is 7 bytes when encoded with UTF-8
- "caña" != "caña"
  Different codepoints can render to the same glyph.
  
  Example: U+00F1 is the single latin character "ñ", but "n" + combining tilde (U+006E, U+0303) looks like the same thing
- "ciao".upper() != "CIAO"
  Case sensitivity is not a universal concept across languages.
  
  Example: in the Turkish locale, the uppercase of "i" is "İ", a capital I with a dot above it. See also this data about case folding

An example use case for splitting strings: chunking messages at word boundaries, instead of at a naive byte size limit that potentially splits glyphs. Read more at Chunking strings in Elixir: how difficult can it be?, in which the author used bstr

MISCELLANEOUS a

Some interesting characters / glyphs / codepoints:
- U+1242B: 𒐫, which is just really big
- U+FDFD: ﷽, which renders very different between my Windows, Android, and Apple devices
- U+1F438: 🐸, the only emoji the the animals-amphibian category, which is the only category with one emoji (EDIT: I wrote about this)
- Five U+25EF joined with U+200D: ◯‍◯‍◯‍◯‍◯, which Whatsapp rendered as the olympic rings symbol for one month in 2016 (source)
- U+FFFF: , reserved as a sort of null codepoint
- U+FE0F: variation selector, and what I call "emoji updater" in my head. Example: \u2764 is 'heavy black heart' ❤, whereas \u2764\ufe0f ❤️ is 'red heart emoji'. This doesn't work on Android, though - maybe they both point to the same glyph in Android's emoji font.
- జ్ఞా : a Telugu symbol made of several codepoints that crashed Apple devices briefly in 2018 (explanation)
- U+A66E: ꙮ, a stylized "O" that only appeared in one 15th-century manuscript when a scribe wanted to add some flair to the spelling for "many-eyed seraphim". It's called the Multiocular O.
Vim tip: (normal mode) ga
Shows the codepoint of the character under the cursor. See also g8.
- Example: with cursor over ✓, ga echoes <✓> 10003, Hex 2713, Octal 23423
Vim tip: (insert mode) <C-v>u / <C-v>U
Input a 4-char / 8-char hex codepoint.
- Example: i<C-v>u2713 will insert a check mark character ✓
Windows tip: Win + . opens an emoji picker
Apparently ffmpeg can encode/decode to colored teletype output with ANSI sequences? Need to test this
Similarly, GIMP can convert an image to ascii art. Need to test this too
A small perk of monospace: clicking on skinny characters like "." or "l" is easier with a fixed-width font than a variable-width font
