Everything fits in UTF-16 (or UTF-8 for that matter). However it's true that many/most emojis don't fit in a *single* 16bit value and require two UTF-16 (or multiple 8bit UTF-8 values) to encode them. Since the NSString APIs assume a 16bit character width, that means an emoji will generally be treated as two characters as far as they are concerned, but that's not really a problem and current gnustep-base can/does work for emojis (for instance, sending UTF16 to mobile phones). _______________________________________________ Gnustep-dev mailing list Gnustep-dev@gnu.org https://lists.gnu.org/mailman/listinfo/gnustep-dev
