Making a new Font is a time-consuming yet rewarding task. Making a Devanagari Font with Indic Shaping features in Open Type Design is especially challenging. This book hopes to address this issue by going into the details of the process involved, by discussing the relevant Unicode Blocks and Shaping features threadbare.

Indic Shaping Features
There are two principal features in Open Type design, namely Glyph Positioning (GPOS) and Glyph Substitution (GSUB). Each feature has the shaping code layouts as below, which we can use during Font Design.

AboveBaseMarkPositioning (abvm)
MarkToBase-attaching anchor of mark glyph with base glyph
AboveBaseSubstitutions (abvs)
Ligature-replacing overlapping glyphs with new drawn smaller glyphs that do not overlap.
Akhands (akhn)
Ligature-replacing क +् + ष combination glyphs with new drawn ligature क्ष glyph
BelowBaseForms (blwf)
Ligature-replacing क्र ् →  क्र्
BelowBaseMarkPositioning (blwm)
MarkToBase-attaching anchor of mark glyph with base glyph
