Please note that substringToIndex does only sometimes return a valid string. I just tried: NSString *a = @"𝍢"; // COUNTING ROD UNIT DIGIT THREE NSLog(@"%s a \"%...@\"",__FUNCTION__, a); // ok NSString *badString = [ a substringToIndex: 1 ]; NSLog(@"%s a \"%...@\" badString \"%...@\"",__FUNCTION__, a, badString); // ← this never shows // because "badString" is not a valid string at all (I would have expected some log message though). NSRange aRange = [ a rangeOfComposedCharacterSequenceAtIndex: 0 ]; NSString *goodString = [ a substringWithRange: aRange ]; NSLog(@"%s a \"%...@\" goodString \"%...@\"",__FUNCTION__, a, goodString); // this works ok and contains the first "character" in of string "a". I admit that it is rather unlikely that this will be a problem with normal Korean text (but I know nothing about Korean scripts).
