I have a simple grammar that just handles comments.
When I generate a Java parser and feed it a comment with a copyright symbol in it, it works (does not complain about unexpected tokens).
When I generate a C++ parser and feed it a comment with a copyright symbol in it, it complains about an unexpected token.
In my Lexer options, I have set charVocabulary to:
charVocabulary='\u0003'..'\uFFFF';
My testLiterals Lexer option is unspecified (the default). I have also tried True and False for the testLiterals option.
I have also tried:
charVocabulary='\003'..'\377';
I'm sure that copyright symbols are not the only characters I will have problems with.
How can I make the copyright symbol acceptable to ANTLR generated parsers?
Thanks!
Tim
