Custom path matching regex

Currently I have seen that the regex (DeepLinkEntry.PARAM_VALUE) is "([a-zA-Z0-9_#!+%~,\-\.\$]*)".
However I have url deeplinks that contains other characters, for example '&'.
https://www.mycompany.com/foo%20&%20bar

So they will not match.

The proposal is to allow the client to customize this regex. (Maybe using meta-data tag in the manifest?)

Thanks.

Start by locating DeepLinkEntry.PARAM_VALUE and the manifest metadata handling; verify how the example URL containing '&' is parsed. Define the customization mechanism and its default behavior, then add coverage for the example URL before considering the issue done.
