Does any of you know whether nxhtml has the capability to convert

The following should work:

   (defun expand-html-encoded-chars (start end)
     (interactive "r")
     (save-excursion
       (goto-char start)
       (while (re-search-forward "&#\\([0-9]+\\);" end t)
(replace-match (char-to-string
           (decode-char 'ucs (string-to-number (match-string 1))) )
          t t))))

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
