“understands” is a bit of a mouthful (provided that you are serious at
all). Let's say I happened to mess around a bit with the fontset stuff
lately.

I have downloaded the ETL font for IPA now and I realize that my
suggestion is flawed, because this font is not encoded in ISO
10646. (I should have thought of that.) You could add a CCL program to
do the necessary encoding (to “MuleIPA-1”) on the fly when displaying
the IPA repertoire from the `mule-unicode-0100-24ff' charset[1]. But
I think that's messy, isn't it?

So your original suggestion is probably better. But I personally
don't know how to do this offhand.

To the OP: Other than following Kai's advice regarding ucs-tables.el
you could let Emacs display the IPA characters in misc-fixed. That
font comes with XFree 4 and contains most (but not all?) of the IPA
characters:

(set-fontset-font 
 "fontset-egoge" ; Replace this with the name of your fontset.
 '(332240 . 332367) ; First and Last IPA chars in mule-unicode-0100-24ff
 "-*-fixed-medium-r-*-*-14-*-*-*-*-*-iso10646-1")

But this has still the problems with `C-s'&Co. as Kai already
mentioned.
