Oh, I wasn't suggesting that they should be updated. Just that there
should be some way to get at the original data.

The mechanism used in 3.1 is sufficient. I'm mostly concerned that it's
*possible* to recover the data; convenience is of secondary importance.

Calling sys.setfilesystemencoding('iso-8859-1') right at the start of the
code eliminates most of the issues. It's just the stuff which happens
before the first line of code is executed (sys.argv, os.environ, sys.stdin
etc) which was problematic.

[BTW, it isn't just Python that has problems. The directory where I was
performing tests happened to be an svn checkout. A subsequent "svn update"
promptly crapped out because I'd left behind a file whose name wasn't
valid ASCII.]
