Non-ASCII characters are not legal uri characters.
Look at section 2.3 of "http://www.faqs.org/rfcs/rfc2396.html".
You see there "unreserved = alphanum | mark" with with "alphanum"
defined in section 1.6 as the ASCII letters and digits.

See also section 2.1 ("URI and non-ASCII characters"). It tells
that non-ASCII characters should be utf-8 encoded and then uri-escaped.

Thus, the handling (by "urllib")
of non-ASCII unicode characters seems to be correct.
