I don't think a flag is the right answer.  

We have a a simple auto-conversion model.  The client encoding is
converted to the server encoding automatically as the data are written to
the server.  

We could handle the whole thing by requiring the API library to use one
consistent encoding.  If *everything* is UTF-16, then autoconvert becomes
a no-op.  

The other way is to handle parameters the way we do columns: each has its
own encoding.  

Let's keep the from-to model and not adopt a flag-based override.
