Are you sure the keyboard inputs u+200D here? I am not sure that all -
er  - *any*  keyboard  layouts available  for  Malayalam on  GNU/Linux
actually uses u+200d.  (And I find chillus forming without U+200D).

Are you sure this should be the rule, linguistically?

Did you mean  `no combination exists int he  font'? Or `no combination
exists in the language'??


If it  is the  first (no conjunct  in the  font) think you  are wrong.
Consider the following situation:-

u+0d31 + u+0d4D + u+0d31 + u+0d4[A|B|C].

u+0d31 + u+0d4D + u+0d31 is a required conjunct, (refer the TDIL april
2002 issue, page 40 of the PDF),  but assume a font does not have this
conjunct.

Your suggestion, if  I understand you correctly, is  that left side of
u+0d4[A|B|C] should be  placed around the second U+0D31,  which IMO is
wrong,  because  the user  will  now  pronounce  the `ra'  separately,
instead of the grammatically correct `tta'.

I am subject to correction though.
