Earlier quoted context omitted.
I would argue that that complexity should be handled by the screenreader through heuristics rather than the .gemini format itself, based on the desire to keep basic clients very simple (~100 loc). But that’s a really good point!
Heuristics might work for longer text where the sample is large enough to uniquely identify the language, but for single words there is not enough information. If I write "coin" in my text, for example, am I using an English word, French word, or Irish word? The pronunciation varies drastically, and screenreaders have to know what to say.
If anybody ever opens an S&M themed bakery, the problem will be accentuated.
