I'm not sure if you find a std-verion, that will work with utf-8 here.
I have checked the standard and case conversion that is present in
locales is definitely not able to perform case conversion on
variable-size encodings. Even the batch version is defined in terms
of per-character conversion.
Unless I'm missing something, standard is quite restrictive here.

Pavol
