When I use German words as identifiers (I try to avoid this, but
sometimes translating to English would just confuse everybody), I do use
umlauts. I have also used Greek letters for physical quantities (e.g., ω
for angular velocity).

Yeah, editor support is a problem[1]. For my code with German identifiers
it is very unlikely that anybody who doesn't use German daily (and hence
already has the need to type umlauts) will ever have to edit it. The
Greek characters are in private code only.

[1] I use vim. Digraphs are a bit awkward but good enough for medium
    rare[2] characters. I don't know how to type characters not on the
    keyboard[3] in VS code or PyCharm or Emacs or whatever others are
    using. "I can't edit your code because I can't type that variable
    name" is certainly not something I want to hear from my colleagues.

[2] Pun not intended.

[3] Includes compose-sequences, if the keyboard has a compose key.
