Strange.  I guess the only way of investigating this is to step with
GDB into the code which renders the mode line, and see which font
specifically is being used there?

Btw, do I understand correctly that the problem you see is the
incorrect location of the dot-like diacriticals above the letters?  Or
is the problem something else?  (I don't read the Tamil script.)
