Update: after talking to Lars during QtCS, he said that he thinks the
QTextCodec API is poorly designed and should be replaced. I agree. But that
doesn't mean we need to remove the *functionality*, just deprecate the API.
I'll bring this up during the QtCore session tomorrow to see if we want to
invest time creating a new API, hopefully for 5.15, so code can begin porting
before the 6.0 time. That way, we could move QTextCodec out of QtCore.

This is now TBD, depending on finding a good design and whether it can be done
incrementally in QTextCodec.
