No, *you* won't see any problems with it.  The problems are entirely a
matter of style and clean internal APIs.  I think it was Aidan (or
maybe Ben) who deliberately changed that particular API in a backward
incompatible way.  I *know* that that implementation is going to
change radically in the future (it depends on Mule charsets, which
will eventually be reimplemented in terms of Unicode code point
blocks), so I really don't want to be bound to maintain any more
backward compatibility in that area than absolutely necessary.

OK, I'll work something up for x-symbol and get it committed.
