Trouble with accents and diacritics

I use Zoom to teach Scottish Gaelic, and since the last big update (I’m on Version 7.1.5), I have been unable to get accented letters in Team Chat. They work fine in the chat of a live call, but when messaging through the Zoom app outside of a call, they don’t work. My usual method is ctrl + ` for a grave accent, ctrl + ‘ for an acute, etc. (And before someone suggests using the ALT codes with the number pad, I can’t because I don’t have that number pad.) And my backup method of using the Windows emoji panel (via Windows key + ;) isn’t working either because I have to click the desired character at least fifteen and sometimes twenty or thirty times before it actually appears in the text, which is intolerable. 

I’m desperate for a way around this problem or for it to be fixed in the next update, because in my language, a missing accent is the difference between féis, “festival” and feis, “sex,” and about a thousand other pairs of dangerously similar words, and it’s hard enough already for the students to get their heads around without that! 😅

Any help would be deeply appreciated!
