It very depends. Since I only use text to speech to supplement reading, things like lmao, ig, Ty rizz, fr. Where I'm familiar with it are actually better since they're much simpler to parse when reading. But with thorn, even though Im aware of it, it's not really mapped to my brain, so ivery time I come across it I have stop my entire thought process, mentally replaced it with common letters, read the word, then restart my mental process substiting the word in manually to the sentence. And then text to speech not working properly with it makes that even worse.
