What you call the "Unicode patch" I think is merely a patch that
redefines tables from being 8-bit to 16-bit. Unicode now exceeds that
number. So it is dead.
You can use Flex with Unicode by merely feeding it a UTF'8 input
file. Then the pattern "<string>" will match the same string in the
generated lexer. For Unicode character classes, one has to recompute
them in terms of UTF-8 regular expressions. I posted some such
functions written in Haskell here earlier.
