Localization: problems with toupper/tolower transformations of latin characters.

[Jan Pfeifer]

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 ? Or is the library missing ?

(I tried different locales, as commented in the code, and using UTF-8
for encoding)


thanks in advance for any help/pointers!
