Currently our code works with UTF-8 byte sequences not unicode codepoints
because thats how tokenizer.c is structured: messy and not generalizable (easily) to things beyond devanagari. How far this can be improved (without too deep surgery) is not quite clear yet.
In other words, this generality is nice to talk about but easier said than done at the moment.
