Case insensitive autocomplete doesn’t work with Cyrillic letters

[pepelsbey]

Describe the bug

Case insensitive autocomplete doesn’t work with Cyrillic letters, but works with Latin ones.

To Reproduce

1. Create two folders:

• mkdir Latin
• mkdir Кириллица

2. Type cd l and press Tab
3. Type cd к and press Tab

Expected behavior

• cd Latin/ suggest on step 2
• cd Кириллица/ suggest on step 3

Desktop

• macOS
• Latest ohmyzsh
• zsh 5.8
• iTerm2, Terminal

Additional context

• Suggest only works for Cyrillic if you explicitly type cd К
• My .zshrc is default, I’ve just installed it

I think I fixed it by adding a custom group to completion.zsh, but it doesn’t look like a reliable solution. It’s not just Latin and Cyrillic out there, right?

if [[ "$CASE_SENSITIVE" = true ]]; then
-  zstyle ':completion:*' matcher-list 'r:|=*' 'l:|=* r:|=*'
+  zstyle ':completion:*' matcher-list 'r:|=*' 'l:|=* r:|=*' 'm:{а-яё}={А-ЯЁ}'
else

(And I still have no idea what I just did there, but it kinda works).

Please, don’t forget about Cyrillic letters from other languages, like Ї, Ґ, Є, Ў.

AFAIK, there are also specific letters in Bulgarian and Serbian languages (needs investigation)

Absolutely! That’s what I’m talking about. It wouldn’t make a reliable solution to list all the letters in the world. We need a universal match. I’d love to suggest it, but I’m not sure if I get what’s going on here: 'r:|=*' 'l:|=* r:|=*'.
