kannada text on emacs 23

[Bala]

Hello,

I am using GNU Emacs version 23.0.60.1 (i486-pc-linux-gnu, GTK+
Version 2.12.0) (package emacs-snapshot-20080228 from
http://ppa.launchpad.net/avassalotti/ubuntu although M-x version tells
me the snapshot date is 2008-03-07) on Ubuntu Gutsy Gibbon (running on
Thinkpad T41). I have installed font packages emacs-intl-fonts as per
directions in the emacs manual online. I still can't see text written
in the Kannada language. All I see are boxes. Please help.

I can see Kannada text properly in other applications though (kate,
firefox, gvim, gedit etc.).

Thanks.
Bala.

The manual has not yet been updated for the ongoing font work in CVS
trunk. You probably need to use opentype fonts with the xft backend,
and have Emacs configured to use libotf and m17n-flt libraries, rather
than using the old bitmap intlfonts package. I have no idea if the
ubuntu package is configured to use those libraries, but in Debian
testing at least, the version of m17n is too old, so any Emacs
snapshot for Debian will not be capable of displaying Indic scripts
properly.

I don't think this is a solution. GNU Emacs 23.0.60 is the Unicode  
Emacs. Therefore it's rather recommended to use Unicode encoded  
(vector) fonts (TrueType, OpenType). I can see good Indic scripts  
support only in Emacs.app, the Cocoa port of GNU Emacs 23.0.60 to Mac  
OS X ...

The online manual needs updating.

I've made a test with launching GNU Emacs 23.0.60 with -Q and letting  
it load some extra ELisp code. And now it displays in the HELLO  
buffer (C-h H) Indic scripts. The extra code is:

It only affects one single fontset. Fonts *I* have installed are used  
here. You would need to apply this for all fontsets you use – and of  
course all fontset sizes, too (fontset-default is derived from an X  
resource).
