Just noticed I did something silly. My input is UTF-8, so the latin characters will be multibyte. The tolower/toupper had no way to know how to handle it. So I converted everything to wchar_t, and it worked for both versions. A got a hint for the C++ version in libstdc++ list: I needed decoupling the wcout from the underlying stdio (?? I guess that's what 'ios::sync_with_stdio(false);' does). And in C one needs to use the w-functions: wcslen, wcscpy, towlower, towupper. thanks, - jan Jan Pfeifer wrote: >hi all, > >I was trying to get propper transformation for upper/lower case >characters in a generic way, at first in C++, but I noticed that the >libc is apparently not converting correctly the latin characters. > >Running the attached code, that tries the C++ and C functions -- later I >found out that libstdc++ uses libc for these, I get: > >$ ./test >C++ version: >Órfão (original string) >ÓRFãO (should be upper case string) >Órfão (should be lower case string) > >C version: >Órfão >ÓRFãO >Órfão > > >Any ideas about what I could be missing ?
