Nice!  I'm sure LibIDN could use some of these modules.  Currently I
copied code from glib and modified it, which is not very maintainable.

Is this NFKC?

One feature request: make it possible to use a particular version of
Unicode.  The IDN stuff requires that Unicode 3.2 is used, and will
return incorrect results if used with a newer Unicode version.  Would
that be problematic to support?  It would be nice if you could keep
this idea in mind when implementing it.
