Hmmm, it seems that your FreeSans.ttf is old.  At least, my
FreeSans.ttf (Version 1.79 of date 16-5-2007) displays that
text correctly.

For Devanagari, by default, Emacs uses an OpenType font that
supports the script `deva' and has feature `rphf'.  If
multiple fonts match that spec, Emacs selects one
arbitrarily.  Perhaps, we must implement a way to reflect
the preference of underlying font-backend.
