It's been 10 years since I've learned C++ during high school, now I'm playing around it again and I'll already facing some problems regarding multi-platform.
I saw that if I want to display special characters on windows, I should use wprintf. However, on *nix systems, it is not necessary.
So, how can I detect what is the current platform, so I can run printf or wprintf depending on it?
UPDATE
I'll open a new question with the error and close this one.
