Cool, that's what I thought of a little later. However, bringing
XStringToKeysym right in would also mean the Xrm hash table used for
the keysymdb. That seemed a little to nasty.

Then I thought it might work to construct a static table from
XKeysymDB and then dump it into some other lookup structure already in
the server. Can the hash table API in dix/resources.c be used, or does
that tie into the resources system more deeply.

Not a bad idea. Nearly everything I've done so far has introduced
duplication from the client side, but I figured I'd try to get it
working before moving orthogonally. It's certainly easier to implement
everything internally to the server rather than introducing a bunch of
external API that might be wrong and can't be removed later.
