Hindi 'r' conjuct appear wrongly

working good.
But the 'Rakaar' in Hindi appears wrongly.
the 'rakaar' is appearing everwhere as the rakaar put on Ta Tha, Da, Dha Characters.
screenshot attached.
The Goldendict Hindi characters are not appearing in Mangal font, i.e. the default Unicode Hindi font of MS windows.
Goldendict uses which font for Hindi?
-- Hariram
