Emacs is still not that good at handling Unicode characters.
It is better to use/recommend the charset thai-tis620 for
Thai characters for the moment.
It's possible to display Thai characters in
mule-unicode-0100-24ff by TIS-620 font by the attached code.
But, I don't want to commit such an adhoc code at this
moment.
(define-translation-table 'thai-tis620-encode-table
ucs-thai-tis620-encode-table)
(define-ccl-program ccl-encode-tis620-font
'(0
((if (r2 > 0)
((r1 = ((r1 << 7) | r2))
(r2 = 0)
(translate-character thai-tis620-encode-table r0 r1)))
(r1 |= #x80)))
"CCL program to encode Thai characters to TIS620 font.")
(add-to-list 'font-ccl-encoder-alist '("tis620" . ccl-encode-tis620-font))
(set-fontset-font
"fontset-default"
(cons (decode-char 'ucs #x0E00)
(decode-char 'ucs #x0E7F))
'(nil . "tis620"))
Another way is to use setup utf-fragmentation-table property
and set utf-fragment-on-decoding to t so that Emacs decodes
Thai characters in utf-8 not to mule-unicode-0100-24ff but
to thai-tis620. But, that is also fairly an adhoc way.
