In a way yes it does.
In C UTF-8 (subject of this mailing list unless I am mistaken) are stored in
char, which are 8-bit wide. So when using UTF-8, you are essentially using a
varying-length encoding (if you stick to char); and part of the C library
does not scale very well with more-than-two byte character sets (as I
unfortunately showed).
Of course, using UTF-32 (that is, towlower/towupper) escapes the problem (as
Michael explained when he opened the thread); but then you should be
prepared to variation of the length of the result, when stored back into
UTF-8 chars; which was Michael's preoccupation as I understood it.

I shall agree with you this is irrelevant to the discussion and I should
have avoided to bring it into the thread, since it only adds confusion, as
you noted.
I am sorry for that.
