Hi
Can anyone please clarify few basic things about how harfbuzz engine does indic
reshaping.
1. In unicode document there are some reshaping rules for indic languages
http://www.unicode.org/versions/Unicode6.0.0/ch09.pdf
2. Also the open type font has open type tables, glyph substitution (gsub) /
glyph positioning (gpos) which also has some info embedded into the font itself
how to get reshaped glyphs.
Is Harfbuzz reading the font and applying the GSUB rules, apply indic specific
rules and reshaping ?.
Also trying to understand how it knows glyphid N is reshaped glyph char C
A very basic high level info would be helpful.
thanks
