A minor correction Terry: it is the number of code units, not bytes. UTF-8 uses 1-byte code units, and from 1 to 4 code units per code point; UTF-16 uses 2-byte code units (a 16-bit word), and 1 or 2 words per code point; UTF-32 uses 4-byte code units (a 32-bit word), and only ever a single code unit for every code point. -- Steven D'Aprano "Ever since I learned about confirmation bias, I've been seeing it everywhere." -- Jon Ronson -- https://mail.python.org/mailman/listinfo/python-list
