Class: HangulShaper

Defined in: src/open-type/shapers/hangul-shaper.ts:28

This is a shaper for the Hangul script, used by the Korean language. It does the following:

• decompose if unsupported by the font: <LV> &rarrow; <L,V> <LVT> &rarrow; <L,V,T> <LV,T> &rarrow; <L,V,T>

• compose if supported by the font: <L,V> &rarrow; <LV> <L,V,T> &rarrow; <LVT> <LV,T> &rarrow; <LVT>

• reorder tone marks (S is any valid syllable): <S, M> &rarrow; <M, S>

• apply ljmo, vjmo, and tjmo OpenType features to decomposed Jamo sequences.

This logic is based on the following documents:

• http://www.microsoft.com/typography/OpenTypeDev/hangul/intro.htm
• http://ktug.org/~nomos/harfbuzz-hangul/hangulshaper.pdf
