The user interface is a real issue and needs to be addressed. It is
separate from the OS interface, though.

A single system often has file names that have been encoded with
different schemes. Only today, I have had to deal with the JIS character
http://i.msdn.microsoft.com/cc305152.932%28en-us,MSDN.10%29.gif>) -- you
will notice that it doesn't have a backslash character. A coworker uses
I use UTF-8. UTF-8, of course, will refuse to deal with some byte
My point is that the poor programmer cannot ignore the possibility of
"funny" character sets. If Python tried to protect the programmer from
that possibility, the result might be even more intractable: how to act
on a file with an non-UTF-8 filename if you are unable to express it as
a text string?
