Hi,
While trying to use urllib in python 2.5.1 to HTTP GET content from
various web sites, I've run into a problem with urllib.quote
(and .quote_plus): they don't accept unicode strings.
I see that this is an issue that has been discussed before:
see this thread:
http://mail.python.org/pipermail/python-dev/2006-July/067248.html
especially this post:

While I don't really want to re-open a can of worms, it seems that the
current implementation of urllib.quote and urllib.quote_plus is
painfully incompatible with how the web (circa 2008) actually works.
While the standards may say there is no official way to represent
unicode strings in URLs, in practice the world uses UTF-8 quite
heavily. For example, I found the following URLs in Google pretty
quickly by looking for percent encoded utf-8 encoded accented e's.

While in theory UTF-8 is not a standard, sites like Last.fm, Facebook
and Wikipedia seem to have embraced it (as have pretty much all other
major web sites). As with HTML, there is what the standard says and
what the actual browsers have to accept in order to work in the real
world.
urllib.urlencode already converts unicode characters to their UTF-8
representation before percent encoding them. Why not urllib.quote and
urllib.quote_plus?
Thanks for any thoughts on this,
Tom
