NAME

       need_uconvert - Tells if a string requires encoding conversion. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int need_uconvert(const char *s, int type, int newtype);

DESCRIPTION

       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 */
          }

RETURN VALUE

       Returns non-zero if any conversion is required or zero otherwise.
