mule question

[François Patte]

Bonjour,

I have a problem with mule: I want to build multilingual texts to be 
processed by xelatex.

I want 3 wrintings (+ latin): devanagari, bengali, tamil. I will 
describe the problem for the two first, for I think that if someone 
helps me to solve the bengali problem, the solution will apply to tamil.

Firstly, I had some problems with devanagari which has been solved 
installing cdac fonts; intlfonts are of no use and create problems for 
indian scripts as far as I could see....

So exit devanagari from the list of problems but, I keep it for comparison.

One can read in
  /usr/share/emacs/22.1/lisp/international/fontset.el.gz:

              ;; Indian CDAC
              (,(indian-font-char-range 'cdac:dv-ttsurekh)
               . (nil . "Devanagari-CDAC"))
              (,(indian-font-char-range 'cdac:sd-ttsurekh)
               . (nil . "Sanskrit-CDAC"))
              (,(indian-font-char-range 'cdac:bn-ttdurga)
               . (nil . "Bengali-CDAC"))

And in
/usr/share/emacs/22.1/leim/quail/indian.el.gz:

(if nil
     (quail-define-package "devanagari-itrans" "Devanagari" "DevIT" t 
"Devanagari ITRANS"))
(quail-define-indian-trans-package
  indian-dev-itrans-v5-hash "devanagari-itrans" "Devanagari" "DevIT"
  "Devanagari transliteration by ITRANS method.")

(if nil
     (quail-define-package "bengali-itrans" "Bengali" "BngIT" t "Bengali 
ITRANS"))
(quail-define-indian-trans-package
  indian-bng-itrans-v5-hash "bengali-itrans" "Bengali" "BngIT"
  "Bengali transliteration by ITRANS method.")



So, if I select devanagari-itrans input method, the devanagari cdac 
fonts are automatically loaded, and I can display devanagari char in my 
emacs window. Using describe-char fonction on a devanagari char, I get:

   character: अ (334533, #o1215305, #x51ac5, U+0905)
     charset: mule-unicode-0100-24ff
	     (Unicode characters of the range U+0100..U+24FF.)
  code point: #x35 #x45
      syntax: w 	which means: word
    category: 1:base (independent) vowel i:Indian
  Properties: script: devanagari; iscii: अ;
    to input: type "a" with devanagari-itrans
buffer code: #x9C #xF4 #xB5 #xC5
   file code: #xE0 #xA4 #x85 (encoded by coding system mule-utf-8)
     display: composed to form "अ" (see below)

Composed by the rule:
The component character(s) are displayed by these fonts (glyph codes):
  �: -FreeType-DV 
TTSurekh-Medium-R-Normal--33-240-100-100-P-119-Devanagari-CDAC (#x2B)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

That is exactly what is expected. But, if I select bengali-itrans input 
method, I cannot get any display of the bengali glyph in emacs (only an 
empty rectangle) and describe-char gives:

   character: অ (334693, #o1215545, #x51b65, U+0985)
     charset: mule-unicode-0100-24ff
	     (Unicode characters of the range U+0100..U+24FF.)
  code point: #x36 #x65
      syntax: w 	which means: word
    category: 1:base (independent) vowel
    to input: type "a" with bengali-itrans
buffer code: #x9C #xF4 #xB6 #xE5
   file code: #xE0 #xA6 #x85 (encoded by coding system mule-utf-8)
     display: by this font (glyph code)
      -Misc-Fixed-Medium-R-Normal--24-240-72-72-C-120-iso10646.indian-1 
(#x985)

Last line shows that, in that case, cdac fonts are not loaded.


My question: howto have cdac fonts loaded in any cas when I select an 
indian script input method?


Thanks for help and sorry for a long post.
