lex/flex doesn't do that :-(

They use small (256-entry) tables for the character types.

I've seen a (long ago) patch to use big tables (which I've read
doesn't work well).

on my (too-long) to-do list, I have an idea which could be developed,
to provide the feature using character-classes.  That is, flex could
be modified (perhaps a month's work...)
