Actually, no, not in the direction you need to enjoy the correct
display of Devanagari. The GDI font back-end is unable to display
scripts that need complex shaping and ligation, and Devanagari
requires those features.
I asked you to try GDI to confirm my suspicion that something is wrong
with Uniscribe, the main font back-end we use on Windows. Now the
suspicion is confirmed.

This is expected with the GDI back-end.
