The title of this post is not broad enough. Avoid emoji as any identifier, whether as strings in your script, IDs on your elements, classes for your CSS, and so on. As soon as you start using emoji, you are blocking some users from being able to understand or use your code. It doesn’t matter how popular the technique becomes (or doesn’t).
If you want to read or type in Hebrew or any other non-western language on a notetaker, be prepared to turn off your speech and essentially trick the braille display if it exists into accepting Hebrew braille. Turn off the speech because otherwise you can’t think in Hebrew while typing since every notetaker embeds Eloquence, and Eloquence absolutely does not speak Hebrew. Want to interact with Hebrew text on your phone and get braille feedback? Hahahahahahahaha no because even if VoiceOver and Talkback support Hebrew, (VO supports Hebrew and will smoothly transition between it and other languages), braille displays don’t. And braille displays absolutely do not support unicode to any extent.
More broadly, regarding non-western languages and code, I don’t think we should continue to ask developers who are not native English speakers and who also do not speak a language which is expressed in Latin characters to make sure their English is good enough so they can code. That seems like an all too arbitrary requirement to me. So it’s not that I’m disagreeing with Adrian, because he’s acknowledging the reality on the ground, and practically speaking his advice is what we need to follow. I just think the whole situation of coding in general and assistive technology in particular being as incredibly ethnocentric as they are is pathetically stupid.
