Indeed it may come down to this, but I have (to the best of my knowledge) a
standard installation of RedHat 8.0 fonts, which is still a popular distro.
Do all RH8'ers have this problem?
It can't be that my fonts lack the square-root symbol, because kmail displays
it, and char-displayable-p returns a list of fonts, suggesting that it
searched for this char and found it someplace. Perhaps there is a mismatch
between the search performed by char-displayable-p and the one in the
display-update routine?
Similarly, xterm is willing to display e-acute, but not for Emacs, so it isn't
"just" a font problem.

Yes, this part of my bug report might be unfixable, but the problem with
e-acute suggests that maybe there is hope.

So (insert (decode-char 'ucs 8730)) works for you? I'm using
-*-fixed-medium-r-normal-*-16-*-*-*-*-*-fontset-standard
with XFree86 fonts 4.2.0-72
