You have to be on a first byte before you can meaningfully apply
NextChar, and you have to use NextChar or else you don't count
characters correctly (eg "__" must match 2 chars not 2 bytes).
Yes, I agree completely. However it looks to me like IsFirstByte will in
fact always be true when we get to call NextChar for matching "_" for UTF8.
