Typing weird symbols

Needful characters

How I input characters not visible on my keyboard varies by platform.

NB Windows is, AFAICT, simply taking the piss here. Straight and curly quotes are entered by numerical codes. I could possibly define better custom shortcuts using PowerToys Keyboard Manager utility. Or automate it away using typgraphical macros. Or edit the document in question from some other OS.

Compose keys on X Windows

Bonus time: Where is that compose key?

Using Ubuntu? The traditional instructions about compose keys, don’t work per default on recent versions.

You can re-enable Compose using gnome-tweaks

sudo apt install gnome-tweak-tool

Then launch Tweaks

1. Go to Keyboard & Mouse.
2. Choose something other than disabled for the Compose Key option.

I set Compose to be Capslock because, like hundreds of millions of computer users, I have never pressed that key deliberately to get capital letters and it seems unlikely that this will change in the coming decades.

This all means that e.g I now type ü as Capslock+" u and “ as Capslock + < ". Which is reasonably mnemonic if you look at a US keyboard layout. Bonus: disables caps lock.

As of the last few days, my computer starts forgetting the compose key settings when it wakes from sleep. Putting the following command in the X11 start up apps list does the job:

setxkbmap -option compose:caps

Now I can treat myself to a caret.

In fact for me, as of recent history, this setting has joined a long list of settings that my laptop now forgets after waking from sleep. So, the downside is that now you can end up with the Caps Lock key actually locking in into ALL CAPITALS BECAUSE YOU ACTUALLY SOMETIMES PRESS IT NOW SO HOW DO YOU DISABLE CAPS LOCK? There is an annoying workaround:

You can run the setleds -caps command from within a console. To get to a console, press Ctrl+Alt+F1, and press Ctrl+Alt+F7 to get back to where you were.

I’ve also seen the following recommended:

xmodmap -e "clear Lock"

You can alternatively (additionally?) enable ISO_Level3_Shift which does a similar thing AFAICT but with less configurability and less documentation online

Launch GNOME Tweaks

1. Go to Keyboard & Mouse
2. Click on Additional Layout Options
3. Expand Miscellaneous compatibility options, check Enable extra typographic characters

It is not clear to me how I enter Greek characters using either of the above methods. There is something called a dead_greek key? Is that real?

Or I could memorize some 4-digit unicode code points and enter characters via Ctrl-Shift-U. That would be a great use of my brief and precious time on this sweet, sweet earth.

But which Compose shortcuts exists? There is no canonical list and you kinda need to guess what happens on your local computer might vary. The Gtk list is a good start. There is an encyclopedia of these symbols at fsymbols.com, although only a subset of the shortcuts listed there work on my config. And you can, hypothetically, define your own. The wikipedia list has the most common examples. The local version is supposedly in a file like /usr/share/X11/locale/am_ET.UTF-8/Compose but for me this includes mostly Ethiopean input methods and not the basic stuff, so I give up for now.

Emoji

In every environment, including ones that don’t have good emoji support or are locked down by sysadmins who hate fun, you can use the emoji search page and reference emojipedia, which is a votimg member of the unicode consortium according to wikipedia, so they must be authoritative.

Sometimes it is hard to type or view emoji. The :emoji: syntax allows us to refer to them via “shortcodes” such as :roller_coaster: for 🎢.

I’m not sure what, if any, the canonical list of these shortcodes is but the emoji cheatsheet will do. The github emoji system is aligned to that, I learned via emojify. For this blog, the ugly-lookin’ and slightly divergent pandoc list was handy. One can also use emojipedia dictionary on macOS which is an OS-integrated dictionary of emoji.

Also important: sardonically rating emoji: ants, horses.

Finding that weird character

There is a nifty web app which solves a lot of these problems for one, called tell.wtf. Give it a go. You can scribble a character and it tells you the unicode translation.

Similarly, shapecatcher lets you sketch it in the browser.

Unicode character search and Unilist and copybar all provide classic style search. Probably the most popular is getemoji, the emoji-finding website from emojipedia.

If you then need to encode it to code points or UL encoding or whatever, see the many web-friendly encodings in the amusing Cryptii app and r12a >> Unicode code converter.

Advanced character molestation

Combatwombat’s Lunicode.js is full of programmatic unicode mangling tricks, e.g.

Wonky alternatives to the usual characters.

చօղҟվ ąӀէҽɾղąէìѵҽʂ էօ էհҽ մʂմąӀ çհąɾąçէҽɾʂ.

One can play with it at Lunicode.com.

Crucially, it supports Zalgo text, and various other stupid stunts from /r/Unicode/. (In fact Zalgo text is a cottage industry.) I’m more of a trap text person myself obvs.

qaz.wtf Unicode Text Converter gives you a menu of quaint text transformations.

Misc

Fun fact: It takes reading of the spec to discover that Emoji are banned from YAML 1.1, which is an important text encoding system. You can use escape sequences, but only in double quoted strings.

So, to write the subtitle of this page for YAML 1.1, you could say

"Writing with \U0001f195\U0001f41c\U0001f41c"

I think this is fixed in the more recent YAML 1.2.
