A password (which is part of the "userinfo" nonterminal) may not
contain unencoded "?":s anyway.  You have to use %3f.

   userinfo      = *( unreserved / pct-encoded / sub-delims / ":" )
   unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
   pct-encoded   = "%" HEXDIG HEXDIG
   sub-delims    = "!" / "$" / "&" / "'" / "(" / ")"
                 / "*" / "+" / "," / ";" / "="
