lower() {maybe others} should mention that if used with
string object [not unicode object] it's likely the that
encoding will change unde some locales [eg pl_PL makes
it from utf8 to latin2]!!

or this hsould be put in the beginning of the doc in
str as a general WARNING/NOTE:

Mark, do you have any thoughts on this one?

A doc-patch would be nice.

I don't like the general situation either. Unicode doesn't
behave like this and I don't think string.lower() and
.upper()  should either, but there are users out there who
think differently, so we might want to add a parameter which
then allows modifying the type of mapping:

string.lower(map='ascii')
string.upper(map='latin-1')

etc.

Just an idea. 

PS: I'll be offline for two weeks now, so don't expect any
more comments before then.

I tried to come up with a doc-patch:

I'd like to see an example that shows this change from utf8
to latin2.

Closing the bug report.
