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.
