It depends on what you want to do. It doesn't alter the
encoding/decoding, it alters how printf (and other functions behave).

Not completely sure what you're asking, so a few points:
* The application should be calling setlocale, not a library.
* Using glib does not preclude you from having to call setlocale.
* You should call setlocale if the C locale isn't appropriate for
you. It's 7 bit ASCII, so if you have an "á" somewhere then
yes, you probably need to call it.
You might want to consider reading the setlocale(3) man page and/or
section 7.11.1 of the C11 standard (or the corresponding part of C89 or
C99—I don't have those handy, though, so I can't give you the section
number).
