Hi,
I hope this is the right list to post this question. I've just been
attempting to convert a grammar from ANTLR 2 to ANTLR 3 --- I am an
ANTLR newbie, however, so forgive me if this is a stupid question
--- but I am trying to convert the following from a lexer rule:
'\177'..'\377'
ANTLR 3 doesn't recognize that syntax for string literals. I
searched the wiki and the ANTLR 3 documentation page and did not see
any mention of the exact definition of the escape sequences that
ANTLR 3 recognizes (for octal character constants in particular).
What is the ANTLR 3 equivalent of the above?
