Hi Carsten and Andreas,


thanks to Kenichi Handa, here is a proposal to fix the issus mentioned
below. I tested it in emacs 22 and 23 and it seems to work just fine.

Carsten, as always if I use some new elisp construct, please review the
patch. I used `eval-when-compile' and `defsubst' to inline the
char-to-string function, since it might be called very often, depending
on the amount of text passed to emacs through org-protocol.


Andreas, could you check if it works for you, too?
