Thanks for your reply. Scheme can't contain ?. RFC3986 definition of Scheme (https://tools.ietf.org/html/rfc3986#section-3.1) scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." ) Delimiters is lavf "schemes" can contain options, and ? should not be part of schemes. So it is not suitable to add ? to the list of delimiters, although it can reduce one search.

Simply add ? to the list of delimiters,and add comment.

Although not a standard URL, is it necessary that protocol can contain "?"
