I think the documentation for those functions is simply badly worded. The "width in bytes" it returns is not the width of the rune (which as jmf notes is simply an alias for int32 that stores a single code point). It means the UTF-8 width of the character, i.e. the number of UTF-8 bytes the function "consumed", presumably so that the caller can then reslice the data with that many bytes fewer. -- http://mail.python.org/mailman/listinfo/python-list
