How does this change with the coming of Unicode and character vs. byte semantics? Obviously we would be safe saying \b in a character class since this is a logical representation of the character, but is \010 still equal to backspace in Unicode/Utf 8/Utf 16/etc.? I worry that assumptions I have always made about the ASCII character set will no longer hold true in the brave new world of i16n. -- Today is Boomtime the 37th day of Chaos in the YOLD 3168 Umlaut Zebra über alles!
