Typing weird symbols

1 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 typographical macros. Or edit the document in question from some other OS.

On macOS, there is a helpful character palette which appears if I type ^-⌘-Space. NB the default characters it searches over for me are not useful. Configure it to have more useful characters.

2 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 memorise 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 exist? 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 Ethiopian input methods and not the basic stuff, so I give up for now.

Bonus time:

• Cross-platform way to enter Unicode characters
• Using Unicode on MacOS

4 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.

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.

5 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, Lunicode 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 us another menu of quaint text transformations.
