The GlyphSubstitution
interface is implemented by a glyph substitution subtable
that supports the determination of glyph substitution information based on script and
language of the corresponding character content.

substitute
Perform glyph substitution at the current index, mutating the substitution state object as required. Only the context associated with the current index is processed.- Parameters:
ss
- glyph substitution state object- Returns:
- true if the glyph subtable was applied, meaning that the current context matches the associated input context glyph coverage table
