Ofcourse, it is widely used in all indian languages. For example അവന്
means "for him" അവന് means "he" the difference is just that zwj and the
rendering will also change to show another character. It is similarly
used for all indian language and actually should be added to
inscript-dev-keytable itself. and its indispensable for the keymap
support of any indian language.

These sequence causing crash are not any usage of
malayalam(but there may be), they are
just a random key presses of the choice of keystrokes available;-)
Below is the result of what i get as i open emacs and do the
following

The above
similarly i get many hangs for other key combinations like
C-u C-\ malayalam-inscript RET kra
there k can be many other letter probably those ones which can join with
"a"i.e. a="ോ" for me.
interestingly this crash dont happen with emacs' own keymap. But only
with the xkb's layout.
k is ക but that can also be i: ഗ but not D:അ
t is ൂ
anyway all time, "a"(ോ) is creating some problems like if ae or qw makes the characters maped
to e and w to display twice. May be a is giving an extra space
considering the letter to be included usually between the two parts of
"ോ"
i am using meera and surprisingly with rachana font, the above specific
bugs are not there.. still it too crashes at some point which i am yet
to track with..
Other than crashes, the display also gets weird at some time for some
random key sequence with malayalam characters
"രോപ്ുോപര്ുേതോപ്തകോര" this is an example of such a thing.
The picture below shows the rendering difference between that in emacs
and in gedit.
But emacs too makes the rendering perfect at times like when that
text is selected for yanking. The gedit too is not perfect in rendering the
above sequence. Avoiding those dotted circles are the thing avoided
to make perfect rendering for gnome.

Hi again,
Though the errors reported at the last mail can be adjusted for the
moment, I have a more Serious Problem. I could get the Perfect rendering
in emacs in general But the text area of Po-mode, where it is primarily
needed, is rendering in the old type. I didnt yet get why that buffer alone is
not taking the changes. Tried changing the fontset and
composition-function-table but no way out!:( . The strings as entered to
the po-mode after finalising with C-c C-c is rendered perfectly, but it
fails where it matters i.e at the text edit area, the buffer named
"*po-filename*" where po-filename is the name of the po-file being
edited. The real joy of getting emacs with malayalam rendering comes
when it helps in serious translation works like that of the gnu.org
pages . Sadly the very same got affected :( All other buffers i have
checked so far works perfectly.
Thanks a lott

What do you mean by "old type"? No composing? Please show
me the result of C-u C-x = on a Malayalam character that
should be composed with the following characters. What is
the value of auto-composition-mode in that buffer?

As I've never used po-mode, I don't know how to reproduce
what you did. Please show me the exact recipe to reproduce
that problem.
