I’m not sure that we guarantee that we will always try things in order. I

As I said in my mail to Adian: that is the main part of the code
(seems less sophisticated than yours, though)
Here’s an implementation with the nice property that where many TeX escape
sequences map to a single character, repeated calls to #'TeX-to-char-region
followed by #'char-to-TeX-region will preserve the original TeX escape:
http://www.parhasard.net/xemacs/TeX-escape-region.el.html
Requires this patch to regexp-opt.el:
http://www.parhasard.net/xemacs/regexp-opt.el.diff
and also the latest beta of the the elib package; or you can stick Simon
Marshall’s unique.el somewhere in your load path.
