Emojis are not part of a living language. They're drawings. But yes, they're outside the BMP. In any case, they're often represented by more than one codepoint anyway, so whether we used N*2 UTF-16 code units to represent them or N UTF-32 code units, it makes no difference. Your code needs to know how to deal with them, where to properly break, how to combine them, how to calculate the width, etc. Also note how they'd be represented by N*4 bytes in UTF-8, which means all three representations take exactly the same amount of memory. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
