Thank you for your advice.
But I think converting the encoding before lexing may be spend additional
time and memory...
another question:
ANTLR is much powerful and controllable than other parser/lexer
generator,but I think the size of the generated code seems much more bigger
than any other I used(such as lex,yecc,lemon...).Are there any advice to
control the code size? A 7M lexer I still feel horrible.%-|

Kind regards
