[HarfBuzz] Issue with Sanskrit 2003 font

[Khaled Hosny]

Happy holidays everyone :)

While testing an issue¹ with XeTeX rendering of Devanagari using
Sanskrit 2003 font², I noticed that the Harfbuzz output for the string
“मन्त्र्यमाण” differs from that of Uniscribe (or ICU), but I know nothing
about Devanagari to tell which is correct, so I’m reporting it in case
it is a bug.

Regards,
Khaled
