need_uconvert - Tells if a string requires encoding conversion. Allegro game
programming library.
#include <allegro.h>
int need_uconvert(const char *s, int type, int
newtype);
Given a pointer to a string (`s'), a description of the type of the string
(`type'), and the type that you would like this string to be converted into
(`newtype'), this function tells you whether any conversion is required. No
conversion will be needed if `type' and `newtype' are the same, or if one type
is ASCII, the other is UTF-8, and the string contains only character values
less than 128. As a convenience shortcut, you can pass the value U_CURRENT as
either of the type parameters, to represent whatever text encoding format is
currently selected. Example:
if (need_uconvert(text, U_UTF8, U_CURRENT)) {
/* conversion is required */
}
Returns non-zero if any conversion is required or zero otherwise.
