Re: unicode editing

["Tim Cross" <tcross@xxxxxxxxxxx>]

Hi John,

check the emacspeak mail list archives. Raman posted a message quite
recently regarding changes in the latest version of emacspeak and the
handling of unicode. It includes details of the unicode.txt file and how to
set it up. I suspect the site you have found has information that is a
little outdated. 

The other thing to consider is upgrading to emacs 23. A lot of work has
been done since emacs 22 to improve how emacs deals with multibyte
characters/unicode. You will likely get the best results if you run emacs
23 and a recent version of emacspeak. Emacspeak has been updated to work
best with emacs 23.

Debian has an emacs23 package in the unstable archives. For ubuntu, there
is a PPA for emacs23 and it will likely be included in the new version
(scheduled for release this month). You can also build from CVS sources,
but you need to make some modifications if you want to also use
debian/ubuntu elisp packages.

There are two types of people in IT - those who do not manage what they 
understand and those who do not understand what they manage.
