[antlr-interest] ANTLR wanting to consume weird characters when using negation

[Petteri Räty]

I am trying to get the attached grammar to match from one token to the
next. The generated code has this if which doesn't look correct to me:

if ( (input.LA(1)>='\u0000' &&
input.LA(1)<='\u0004')||(input.LA(1)>='\u0006' && input.LA(1)<='\uFFFF') ) {
            	        input.consume();

 }

I don't see why it should consume \u0005 which seems to be some kind of
a non printable character. I am using antlr 3.3. Is this a bug in ANTLR
or am I just doing something wrong?

Regards,
Petteri
