[antlr-interest] string literal token rule not working?

[Monty Zukowski]

You need to set the charVocabulary option, see the documentation about 
it.  ANTLR assumes only characters referenced by the lexer are valid.  
When inverting it only uses that set to invert upon, not the whole 
ASCII or Unicode range.
