You see "code point: 36", and you see that it is the right-hand part
of the alphabet only.  So 128+36=164 is the actual code point you want.

You can look at the font name, for example.  And you can look at the
charset and compare that with your font, to see whether they match.

Argh.

You can't.  But you can do it the other way round: you can tell Emacs
to use the foo font for the bar encoding.  Investigate fontsets in
the Emacs documentation.

With a X11 resource, for instance.  You probably set the font for
your X11 apps somewhere (otherwise it would be "fixed").

Oh, boy.
