as others have suggested, it's already too late to modify -connect and
-assignednumbers.
So what needs to happen to get this standardized is for someone to write
an internet-draft documenting this extension and advance it as either a
working group item or as an individual submission.
In response to later messages:

I think Nicolas was implying that a request from the client to use a
UTF8 locale would cause the server to set up the pseudoterminal it
creates/allocates/... appropriately for the requested locale. But
that's perhaps at odds with the existing strategy within the protocol of
making termios-level details visible on the wire.
