Yeah... in general, you need to decide exactly what kind of sorting you
intend. If you intend to sort individual graphemes (i.e., what we
normally think of as "characters"), you need to segment the string into
graphemes with .byGrapheme and then sort it as an array/range of
graphemes. Sorting Unicode code points is probably not what you want,
and sorting code units is probably never what you want (unless you're
doing byte frequency analysis on UTF-8 or something :-P).
Unicode is a tricky beast.
