Not mine anyway. It happily accepts mostly any characters in the URL
outside the host name. Tested with
<!"$8()(˝§@櫢eee> and it got forwarded
quite nicely.

The validations Squid perform is:

a) The host name must consist of valid charaters [a-z0-9.-]. This check
is hardcoded and can't be disabled without changing the source.
b) The urlpath & query must not contain white space. (space or tab).
This check can be controlled by uri_whitespace in squid.conf. (note: the
encode setting is flawed in Squid 2.2, use either deny or allow)
