too. So if somebody implements non ASCII identifiers because he needs a

But what will the rule be as to whether something's a valid identifier?
Will it have to start with something known to be a letter, or something
not known to be a digit or reserved character?
Afaik the latter. You specify what is not allowed rather than which are
allowed.
Hm that makes it easy to have an incomplete list, that could later
become a problem
half-width spaces etc..., control chars (RTL/LTR...), currently unused
codepoints (that could become anything in future...)
