I don't use surrogates. I only use UTF-8 and UTF-32. But using cygwin's
wcwidth may be worth thinking about. I suppose it will be consistent
with mintty that way; otherwise not?

Using wcswidth isn't very useful in the editor because it has special
requirements, like showing control characters with ^C. That's one of the
reasons I mostly wrote my own, all the special requirements. I always
iterate of bytes, which are converted in a mode-dependent way to ints
(UTF-32). Do you have a case-insensitive compare? Because I limited that
to ASCII.
