Ah, I'm afraid not.  How about ⠾ ---if the implementation uses
utf-16, it has to become two characters, one's code is #xd800 and
another's is #xdf02.
(Or is there a JVM-based Scheme that does handle surrogate pair as
a single character?)

I put my presentation on ILC2003 about multilingualization (m17n)
support on Scheme on web, in which I suggested several operations
that would be useful to write a portable Scheme programs
across various implementations.

More discussion is necessary to nail down what operations
are essential, before start thinking about m17n SRFI, though.
If anybody has ideas/optinions on it, I'm eager to hear it.

That's nice.  Hmm, I need a rather large table to do that, though...
