"Nakula follows the Bombay style of Devanagari, with rounded glyphs and little 
thin/thick variation. Sahadeva is in the Calcutta style, with more angular 
glyphs and greater contrast between thin and thick strokes. The actual shapes 
of some of the glyphs (e.g. initial “a”, retroflex “n”) also differ 
according to the style of the font."

"Chandas font represents Southern (most commonly used today) style of 
Devanagari script. And Uttara font represents Northern style of Devanagari 
Script. These styles are sometimes also called Bombay (Southern, contemporary) 
and Calcutta (Northern, old) pen families accordingly. Uttara is today the only 
Devanagari OTF font which supports Northern variations in simple glyphs and in 
ligatures. "
