RFC3986_Parser accepts invalid URIs containing %
URI.parse('https://www.example.com/search?q=%XX') does not raise an error despite being an invalid URI. A % in a URI must be followed by exactly two hex digits, but the RFC3986 parser does not check that in the URI query. Ruby 2.1 correctly raises an error.

I agree that this is a bug that should be fixed. The implementation automatically percent escapes invalid characters instead of rejecting them by design. However, I don't think that implies we should accept invalid percent escapes already present. Attached is a patch that should fix the issue.
