I\'ve got an international character stored in a unichar variable. This character does not come from a file or url. The variable itself only stores an unsigned short(0xce91)
unichar greekAlpha = 0x0391;
NSString* s = [NSString stringWithCharacters:&greekAlpha length:1];
And now you can incorporate that NSString into another in any way you like. Do note, however, that it is now legal to type a Greek alpha directly into an NSString literal.
