Hi,
To be honest, I haven't tried to use string_algo with encodings
that use variable number of bytes per character.
All algorithms work in character-wise manner, so utf enconding
might not work.
Internaly std::tolower(Ch, Loc) is used to do the conversion.
Try to see if this function works for you. If it doesn't give
the required results, algorithms in the string_algo will
not work either.
Regards,
Pavol.
