Re: Bidirectional editing in Emacs -- main design decisions

[Mohsen BANAN <list-general@mohsen.1.banan.byname.net>]

First let me preface that I am new to this list
(through gmane) and that I am not on top of the
subject matter at hand.

If I am understaning it right, I think your new
decision is right also from a different
perspective.

In that it then becomes consistent with how bidi
works in mozilla/firefox.

Being consistent with the browser is important in
practice. Let me cite an example.

I have been using build GNU Emacs 24.0.50.1 for a
while to exchange email (Gnus) in Farsi and mixed
Farsi/Latin with family and friends in Iran who
use browser based MUAs.

My mixed language text generated with emacs
displays inconsistently in firefox vs emacs24.

For example when I write:

اسم کوچک من محسن Mohsen و اسم خانوادگى من بنان
Banan است.


My first name is Mohsen محسن and my last name is
Banan بنان.

And I think the design decision that you mentioned
will make them consistent.

Thanks for the good work.

Best,

...Mohsen

...محسن
