My fault, should have been clearer. I was trying to demonstrate that
there's a difference between the unix-friendly encodings like UTF-8
and the EUC codecs which only use high-bit characters for non-ascii
text, and the ISO-2022 codecs and Shift JIS.
In the example I gave, 十 encodes in CP932 as '\x8f\\', and the
function gets confused by the second byte. Obviously the right answer
there is just to use unicode, rather than write a function that works
with weird multibyte codecs.
