Thanks, Eli and Miles. The conversion works fine (with uncomposed 
glyphs, that is, points as separate characters, same as in the html 
codes). I referenced the command in an alias:

(defalias 'xhc 'expand-html-encoded-chars)

and then tried to do the same with this function:

(defun reverse-string (beg end)
  (interactive "r")
  (setq str (buffer-substring beg end))
  (apply #'string (nreverse (string-to-list str))))

but it doesn't seem to work, although it doesn't produce errors in a 
traceback buffer. What am I missing?

Thanks,

Ed
