Whi is nl_langinfo(CODESET) different from locale charmap?

Question

I tried using

nl_langinfo(CODESET)

but I got ANSI_X3.4-1968 instead of UTF-8 (which is what I get when typing: locale charmap). Am I using nl_langinfo() wrong? How should I use it?

Answer 1

You need to first call

setlocale(LC_ALL, "");

nl_langinfo always gives information about the current locale.
