The trouble, is when a client talks to a service, it now has to decide
whether to use C String, or UTF-8 string. So, either every application
(or the language bindings) would need to be updated support both formats,
or you'd end up with a situation where only some apps spport C strings,
which wouldn't be good for interoperability. Since there is no compelling
reason for most apps to support C strings, unfortunately I think we'd
end up in the latter situation which isn't a very desirable result.
