I think what you are looking for is the aptly named setlocale() function
from the standard <locale.h> header:

http://www.cplusplus.com/reference/clibrary/clocale/

On my machine, setlocale (LC_CTYPE, NULL) returns the string
"en_US.UTF-8" which is the ISO 639-1 language code followed by a "_"
followed by the ISO 3166-1 alpha 2 country code followed by a "." and
the default character encoding for the locale.

Here's the sample code I used for testing:

#include <locale.h>
#include <stdio.h>

int main (int argc, char **argv)
{
        /*
         * Set the program environment locale to the "native" locale.=20
         * You need to do this if you care about the platform's locale=20
         * because by default the program environment locale is set to
         * "C".
         */
        setlocale (LC_ALL, "");
        setlocale (LC_CTYPE, "");

        /* Get the locale strings */
        char *locale_all =3D setlocale (LC_ALL, NULL);
        char *locale_ctype =3D setlocale (LC_CTYPE, NULL);

        printf ("LC_ALL=3D%s\nLC_CTYPE=3D%s\n", locale_all, locale_ctype);

        return(0);
}

This seems sensible. I suggest we unify the namespaces for internal
access to freekode subsystems, something like:

fk_events_init();
fk_events_close();
fk_locale_init();
fk_locale_close();
...
fk_<subsystem>_<function>();
