Georg, NSString/CFString is conceptually an object wrapping around UTF-16 character array (just like many other string objects). The length 2 returned from your example is, thus, the expected behavior.
When you're creating a string with Universal Character Names that containing non-BMP points, the official syntax is \UXXXXXXXX so it should be @"\\U0001ABCD". > int Char = 0x1ABCD; > NSString *aString = [NSString stringWithFormat:@"%C", Char]; //The > resulting string contains one character with a unicode value of "ABCD". %C takes a short value. You can do something like this: UniChar characters[2]; CFIndex length = (CFStringGetSurrogatePairForLongCharacter(0x1ABCD, characters) ? 2 : 1); CFStringCreateWithCharacters(NULL, characters, length); Aki On 2010/06/27, at 14:18, Georg Seifert wrote: > Hi, > > Does anyone has information on how to use Unicode code points higher than > 0xFFFF. > I need to add some supplementary multilingual plane code points to a NSString. > > I can use something like this: > NSString *aString = @"\\u0001ABCD"; //this prints fine but the [aString > length] is 2 > > But if I have the unicode value as a int (unichar is to small) > int Char = 0x1ABCD; > NSString *aString = [NSString stringWithFormat:@"%C", Char]; //The > resulting string contains one character with a unicode value of "ABCD". > > What is the recommended way to use/create UTF-32 strings in Cocoa. > > Best Regards > Georg > > _______________________________________________ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > http://lists.apple.com/mailman/options/cocoa-dev/aki%40apple.com > > This email sent to a...@apple.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
