get_uformat – Finds out what text encoding format is currently selected. Allegro game programming library.
Synopsis
#include <allegro.h> int get_uformat(void);
Description
Finds out what text encoding format is currently selected. This function is probably useful only if you are writing an Allegro addon dealing with text strings and you use a different codepath for each possible format. Example:
switch(get_uformat()) {
case U_ASCII:
do_something();
break;
case U_UTF8:
do_something_else();
break;

}
