Trouble rendering tamil characters (indic)

[Arun Kumar]

Hello,
 
I am having trouble getting lilypond (on winxp) to display certain tamil (an 
indian language supported by pango-indic) characters. These are of the form in 
unicode as consonant+modifier which results in *one* character in the font 
which represents the modified consonant. I actually find *some* of these forms 
to work but many dont. Note that the character displays correctly in a unicode 
text editor (babelpad).
 
Is this a bug in pango? I have tried lilypond 2.6.4 as well as latest 2.7 but 
have the same problem. 2.6 I believe uses Pango 1.4 and 2.7 I think uses Pango 
2.10?
 
To see if it is really a problem with Pango, I have installed GIMP and GTK 2.0 
which also uses Pango (1.10) and tried its text editor. The text-editor is 
able to display the characters correctly. Only when I generate a PNG or PDF in 
lilypond, does the character not come out correctly. So I dont know if this 
means there is still a bug in Pango or how Lilypond uses it?
 
Any help/pointers would be greatly appreciated.
 
Thanks
Arun
