Subject: Patches for Thai support
Date: Wed, 22 Sep 2004 15:18:15 +0700	[thread overview]
Message-ID: <1095841095.7357.439.camel@pineapple.bkk.thaiopensource.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 878 bytes --]

The handling of composite sequences for Thai is overly simplistic as
regards handling of diacritics.  To give just one example, you can't
have a tone mark over a maitaikhu. There's a Thai standard called WTT
2.0 that gives the precise rules.  WTT 2.0 also has some extensions to
the Kesmanee keyboard layout that are fairly universal on keyboard used
Thailand today. There's an English language description of all of this
at:

http://www.nectec.or.th/it-standards/keyboard_layout/thai-key.htm

Attached is a patch against the current CVS Emacs that fixes the Thai
support to match WTT 2.0.  It's only lightly tested.

There are some more fundamental issues with the support for Thai (and
other South and South-East Asian languages that rely heavily on
combining characters).  More about these later.
