Hello All, I've got a PR [1][2] up which changes the behavior of the UriBuilder implementation. The gist is that we currently do not encode a ? if found in a query parameter name or value. The change is to encode the ? to %3F if found. This seems to be the way that the Apache URIBuilder encodes parameters as do other Jakarta REST Implementations. It seems best to me to encode it for consistency. However, it does introduce a potential breaking change. Please share your thoughts/opinions on the PR or here. Thanks in advance.
