Interesting, the testcase looks the same for me on both IE7 and Gecko trunk (and so does a parallel testcase in Word and OpenOffice)

Tested on two different computer on IE6, 
both show it in correct way, when FireFox, OOo, MS-Word show in the wrong way.

So now I doubt IE6, whether it switch back to Kartika font for displaying "ppra" when others are still in Anjali

Biju, I suggest you test this again with New Firefox nightly builds (3.00 beta)
and report it the status of this bug.

Retested, I see the same issue.
But now I doubt who should handle this
 a) the rendering tool 
 b) or in the font

If font can be made to handle this mark this bug - INVALID
if there is now way in font or by browser mark this bug - WONTFIX
if there is way, ie by changing font specification mark this bug - FUTURE
               and rise this issue in appropriate forum

AFAIK there is no such conjunct in Malayalam. Can you give an example of a word containing such a conjunct?

Praveen,

I too agree with you. There is no such use of a conjunt in malayalam.

Thanks
Ani

Assuming problem is in the FONT, I am marking this invalid.

I came across this when I was writing മല്ലപ്പ്ര a house name. 
Also there is problem when we write റ്റ്ര to make "tra" sound in truck.
(I know instead we substitute Malayalam ട u0d1f.)

If there is no such usage of പ്പ്ര in Malayalam is the reason,
why ൠ ൡ and ഌ are there in Unicode Malayalam.
tell me a word in Malayalam with ൠ or ൡ or its sound sign
and as far as I know there only one word with ഌ sound sign 
(but to write it, we are use ക്ല)

What we have to ask is, is there a rule that say പ്പ്ര can not exist.
I dont see it at 
http://www.malayalamresourcecentre.org/Mrc/literature/keralapaanineeyam/panineeyam.html

Century ago making printing technically easy made us loose Malayalam equivalent of Tamil ன which looks like
http://www.malayalamresourcecentre.org/Mrc/literature/keralapaanineeyam/images/na.gif

also many centuries ago we lost another letter, that sounds in between T and R
for which Kerala Paanineeyam has given a fictitious shape
http://www.malayalamresourcecentre.org/Mrc/literature/keralapaanineeyam/images/ra.gif
if that letter was there we could have used for T when we write TICKET

മുല്ലപ്ര is enough. See how പുന്നപ്ര is written. 

You got it wrong, it is the other way. We support a letter/conjunct only when a proof of its use is given. ഋതുമതി is a word with ഋ and you have given an example for the other character. There are many cases were you can't form a conjunct with ര. For example chroot is ഛ്രൂട്ട് because ച cannot from conjunct with ര. And unicode only encodes base characters. Both examples you have mentioned are base characters and the original case that you opened this bug is about a conjunct and unicode has nothing to do with it. It is all about font design. You can check if any font contains a ppra glyph and if you think there should be such a glyph may be you can add it to any font.
