Fix#5103. By default, Httpclient will encode the URI but
we don't necessarily want that. These modules originally
didn't use URI encoding when they were written so we should
just keep them that way.
See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in
