Nicolas,
OK. I don't know exactly what I'm talking about here as you can see. :)
I'm writing an XML parser/writer/simple DOM, which will input and output
primarily in UTF-32.
This program outputs some information to stdout in the testing process,
and this is also UTF-32 (internally a character is an integer >= 32 bits).
I tried now to use putwchar:
putwchar((wchar_t) buffer[index]);
And the output is the same as if had used
printf("%c", (char) buffer[index]);
That is, non-ASCII characters are garbled.
All the locale settings except LC_ALL are en_US.UTF-8, LC_ALL is empty.
What I'm looking for is a cross-platform way to output some data, to aid
in the testing process. Reading and writing from files will probably be
binary and handled internally in the program.
