httplib employs the "idna" encoding. that leads to
errors in py2exe/cxfreeze. And if forced into the
installer, it draws the 400kB+ unicodedata.pyd (on Win)
in innocent small apps. Otherwise no normal technical
modules draw the unicodedata.

Is that really necessary?

I agree - in most cases, ASCII will be used for hostnames
(where the idna encoding is being used in httplib).

A little helper function to first try .encode('ascii') and
then revert to .encode('idna') would do wonders.

Patches are welcome !
