Well, i am at a very beginner level with Flex. I could see how flex works with it even if it is a ambiguity. Since it matches the rule with the maximum text and we don't allow a new line character in the rule, it works fine. Even in LL(1), it works fine, but throws warnings. So i just thought of suggesting to remove the ambiguity. But do we need to allow comments as part of unicode escapes?
