[antlr-interest] \0 tokenising ?

[Robert Collins]

Hi, I have a file I want to parse, which contains \0 - ASCII NULL
characters as delimiters. I can't seem to get antlr3 to recognise this -
I always get:

 1:1: Tokens : ( ASCIINULL | MINUS | WHOLE | CRC32 | HEADER | NL |
NUMENTRIES | NOWHITESPACE ); at offset 53, near char(00) :

I have tried:
ASCIINULL: '\0'; 
ASCIINULL: '\\0';
ASCIINULL: 0; // errors

Any guidance on this?

-Rob
