I have a STRING token defined thusly:

ESC : '\\' ( 'n' | 't' | '"' | '\'' | '\\') ;

STRING : '\'' (ESC|~('\''|'\\'))* '\'' ;

antlr.Tool, however, doesn't generate any cases in the mSTRING method for any of
the characters 'ghlqvwxz', as well as a few others that I
would expect to be in there, causing parse errors. I'm stumped.
Does anybody know why this might be?
