unicode & Emacs

unicode & Emacs

[Jose E. Marchesi]

Hi all.


I am unable to find the emacs-unicode mailing list. It seems to have
been closed. So i assume this is the right place to post and discuss
unicode-emacs related issues.

I am currently designing and writing a piece of software named EDKIT
(for EDitor KIT). It is basically a set of useful libraries for text
editor development. When dealing with character repertories, character
codes and character encodings was very clear to me that EDKIT should
include native ISO 10646 support in the buffer component as the
internal representation of text. So i started a heavy learn about
character issues. Finally i implemented the EDKIT unicode native
support that is capable to encode the entire 31 bits ISO 10646 code
space in good compact UTF-8 encoding.

I studied the Emacs implementation for character sets as part of my
investigation. While mule offer many nice features i wondered about
some existing plan to implement native ISO 10646 support on Emacs. I
googled some references for a `unicode-emacs' mailing list, but i was
unable to find it on the mail gnu machine.

I also found a proposal in the form `Emacs-Unicode-990824' where UCS-E
and UTF-E was explained. It was on a thread on the `linux-utf8'
mailing list at
http://mail.nl.linux.org/linux-utf8/2001-11/msg00026.html. But no
further references.

There is a emacs-unicode branch on the CVS. Are UCS-E and UTF-E
implemented on that branch? If not, there is any plan for implement
it and substitute the MULE internal encoding?

The goal of my queries is to aid in the development of Emacs ISO 10646
support now that i adquired some design/implementation experience on
those issues.


Many thanks.

emacs-unicode-2 is the branch you want. The internal coding has
already been changed to Unicode there (I'm not sure if it is
UTF-E or some other UTF).

CVS problems (was: unicode & Emacs)

If I understand correctly, the checkout procedure is 

        export CVS_RSH="ssh"

        cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/webcvs/emacs co -r emacs-unicode-2 emacs

but it yields just 

        cvs [checkout aborted]: no such tag emacs-unicode-2

Moreover, 

        cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/webcvs/emacs co emacs

checks out only some documentation.

Am I doing something wrong?

Best regards

Janusz

/webcvs is the webpages repository.
Use /cvsroot instead for the software repository.

The mailing-list emacs-unicode@gnu.org is still alive.  If
you want to join the list, please ask Eli <eliz@gnu.org>.

I don't remeber UCS-E nor UTF-E well now.

Anyway, in the latest code of the branch emacs-unicode-2, we
use the character code space 0x0..0x3FFF7F, and among them,
0x0..0x10FFFF directly corresponds to Unicode characters one
to one.  In buffer and string, those characters are
represented by UTF-8 encoding.

This code is fairly stable on Unix and GNU/Linux.
