Unicode works with emacs23 + latest emacspeak



Tim and Jason,
I took your advice and installed emacs23 from a ppa.  I also upped emacspeak
via svn.  Voila, Arabic multibyte utf-8 encoded characters are being spoken.
The problems I was having with storing and retrieving text with registers
are also gone.

Are both of you running emacs23?   I seem to have been experiencing a lot of
problems with emacs22, I wonder if it should be recommended to run the
latest versions of emacspeak with emacs23.

When it comes time to upgrade to the new version of ubuntu (in 2 weeks), can
this be done with apt?

Thanks again, congratulations to Raman,
John

Jason is correct. You should not mix packages i.e. do not install a debian
package on a ubuntu box and vice versa. While the two distributions are very
similar, they do differ in places and the way things are layed out in the
file system. Mixing the two will sometimes work and will sometimes introduce
difficult to track down and fix errors and sometimes will just break things.


I doubt the existing 'stable' release of ubuntu has emacs 23 as it was (I
think) released before emacs 23 was. However, the new ubuntu version due
this month will probably have emacs 23 in it. So, if your running current
ubuntu, your best bet is add the PPA for emacs 23 and install from there or
wait a week or so for the new version and upgrade to it and install from
there.

P.S. I've not checked unicode stuff yet. I'm in the middle of migrating
systems. Will let you know on Sunday. However, given the changes brought in
by emacs 23, I would suggest that is still the best place to start. If it
still doesn't work, we can then try to determine why not and what may need
tweaking in emacspeak. If it doesn't work in emacs 22, it is likely to be
difficult to get a fix as emacspeak is likely to be focused on emacs 23
rather than emacs 22 since emacs 23 is the current stable version of emacs
and making changes to fix a problem in emacs 22 will likely cause issues
with emacs 23. Handling of unicode in pre-emacs 23 is completely different
from emacs 22 - this is one of the major changes between the versions. As I
understand it, this aspect of emacs was almost completely refactored between
the versions. Changing emacspeak to support both the old handling and the
new is likely to introduce more problems than it fixes and as there are
limited resources, it is unlikely Raman would be agreeable to mods that
complicate the code base for the sake of an old emacs version. (this is just
my assessment, Raman may have a different view and I don't mean to speak for
him - I may be completely wrong)
