I'd like to get a correct CString implementation into GHC's libraries.
I think the CWString implementation we have now is good enough, but
CString should be doing locale encoding/decoding (as you know). At the
same time, we should check all the withCString calls to see whether they
should really be withCAString (since withCString is about to get quite a
bit slower).
Would you be interested in helping with this, or even putting together a
patch? It's probably too late for 6.4, though.

There's no way to replace the handler, I'm afraid.
