That's on purpose, since the mask has just matched. If 0xFFFFFF80
matches, then the max char can't be 127, it has to be at least 128.

Because otherwise you're returning 0xFFFF in the following line:
 if (ret < 0x10000)
 return 0xFFFF;

Ha, funny that gcc doesn't say anything.
I also forgot to #under MASK_*.

Well, no. 1 is a legal value, even though it's handled elsewhere, so the
error message is right.

It's because I'm moving the stringlib #includes up in unicodeobject.c,
and stringlib calls these functions.
