Being honest, imo UTF-8 is only a hack to get unicode on platforms like
unix. Further, processing UTF-16 is much easier, for a lot of
applications faster and for important encodings like chinese more memory
efficient. If UTF-8 was easy to handle, we wouldn't have to convert
everything to UTF-32 on unix to do case conversations, comparisations etc.
