While I'm writing such a thing (adding LRM characters to the string),
I will need a function to tell me wether two strings containing
logical representations are "equal" in order to write my test cases --
for a meaningful definition of "equal".

I read UAX#9 as saying that two strings should be equal when the
logical representation has been transformed into the visual
representation and all LRM RLM RLO LRO and PDF characters have been
removed.  Correct?

Will such a function be usefull for Emacs as well?

Alex.
