Right.  Your second approach is valid when what comes from X is a
real Unicode character, for instance, if you already have a keyboard
that generates those characters.  The first one is valid when you use
a keyboard with dead keys.  The two approaches are complementary and
can be used simultaneously.

In fact, it would be better if Climacs would systematically test for
real Unicode characters as opposed to having them entered explicitly.
The problem is, I am not sure how to test that.  Perhaps everything
above 127 with only a Shift modifier is such a real Unicode
character?
