Hi, I got personal mail (which was reply to my earlier mail) from eli zaretskii, one of the maintainers of gnu emacs. the team seems to be in need of contributors to improve the unicode support. see below

How's your C? Some of the work (a large part of it, actually) needs to be done on the C level. Even if you can only read the code (in C or Lisp) and suggest how to modify it to implement various Unicode features, it's still useful, as others could write the code given your advice. > But i have done some superficial "research" on m17n, i18n and l10n ... > see http://www.coli.uni-sb.de/~oldo/PUB/mls-reqspec.html ... Impressive. We certainly need that kind of overall view of the issues when discussing and coding Unicode support in Emacs. Would you like to be subscribed to the emacs-unicode mailing list? > > mappings, bidirectional editing, Arabic presentation forms, etc. Does > > vim really support those? > combining characters ... hm ahem ... http://vim.sourceforge.net/whyvim.php Thanks for the pointer. However, I cannot see anything there besides support for UTF-8 and other Unicode encodings. Nothing about combining characters, and the Hebrew text in the snapshot is in the wrong direction (which means bidirectional behavior specified by the Unicode Technical Report #9 isn't supported). So I guess Unicode support in VIM is still very preliminary, although better than Emacs's. > Are you on linux-utf8 ?? No. I don't have enough time to read another mailing list, sorry. > Who knows the design that has been made for the unicode support? I attach it below. > Maybe these people could join the linux-urf8 list and > advertise theiir concept and hopefully some others might "step in" do > contribute some code. I'd prefer that people who want to work on adding Unicode to Emacs subscribe to emacs-unicode, and that the work be coordinated there. Please feel free to forward this suggestion to linux-utf8. > Where is the emacs-unicode mailing list?? It's hosted on gnu.org machines. I can subscribe anyone who wants to be part of this effort. > thank you for all the valuable work you do! You are welcome. And thanks for raising this important issue: it looks like a few people are interested enough that they wrote to me and offered help.
