As I learned from the xemacs-beta mail list, Ben is working on
unicode-internal support. I want to learn more about it.
What internel representation scheme shall we use? Is it the same
scheme as in GNU Emacs's emacs-unicode-2 branch (which named
utf-8-emacs)? Or we'll use a different scheme such as utf-16-like? Is
there a unicode-internal branch in the cvs repository?
