The functions in utf8.h/c have precise meaning, and I don't think they
are the cause of the problem.  In theory, we should be able to say:

  aegisvm foo.bar

to invoke the main method in class bar of package foo.  We should also
be able to say:

  aegisvm foo\$bar

to invoke the main method of foo's inner class bar.  The first, as you
have pointed out, is broken, while the second seems to work okay.  I
looked again, and find that in aegisvm.c I have actually forgotten to
convert the command line Java class name into its internal form.  Also, in
the native implementation of Class.define() I have used the wrong
predicate to test the validity of the classname argument.  Attached is
the fix I just committed.  Thanks for pointing out the problem.
