Asset Resolver can't use ? in paths

[dgovil]

Description of Issue

Hi there,
It appears the asset resolver system doesn't allow for ? in the path.
Unfortunately our asset resolution system uses URIs to resolve asset paths so there are a lot of uses of ? and this limitation was causing issues the plugin I was writing.

In the meantime I'm going to use a different character and do an internal replacement before passing to our internal resolver, but it would be great to have a way to support the ? since they're a common token in the URI spec.

Also if possible, I'd ask if it could be documented in the doxygen docs in the interim to a solution?

Some discussion here where spiff asked me to file a ticket for this.
