[Message part 1 (text/plain, inline)]

In nxml-mode, numeric character references (such as  ) are
displayed with the referred-to character following the reference. It
would be nice if html-mode did the same. (The format of these
references is the same in xml and html, so sharing code for this
should be simple.)

I think this functionality should be separated into a new package
because it's useful for character notations of other modes as well,
e.g. Emacs Lisp with #x, C with 0x, Perl with \x, etc.

That does sound exceedingly useful...  Hm...  perhaps I should have a go
at it unless this already exists somewhere?

When I looked at prior art the closest matches were the package rainbow-mode
from ELPA that displays colors by character codes, and prettify-symbols-mode
that transforms characters into alternative representation.  But doing this
using font-lock-keywords is so trivial, it was easier to just put a small
piece of code in ~/.emacs.
