Covered APIs

API	Poznámky k použití
`TibetanShapeToGIDs`	Returns a Tibetan shaped glyph-ID sequence without emitting PDF text
`ApplyTibetanShaping`	Applies Tibetan GSUB shaping and maps shaped glyph IDs through synthetic codepoints for text output
`ApplySyriacGSUBPositional`	Applies Syriac joining-position analysis and font positional GSUB features
`ApplyMongolianGSUBPositional`	Applies Mongolian joining-position analysis and font positional GSUB features
`GetSyriacJoiningClass`	Returns the Unicode joining class used by Syriac position resolution
`GetSyriacPosition`	Resolves an item in a Syriac run to isolated, initial, medial, or final form
`GetMongolianJoiningClass`	Returns the joining class used by Mongolian position resolution, including transparent controls
`GetMongolianPosition`	Resolves an item in a Mongolian run to the positional form requested from GSUB
`AutoShapeSyriac`	Opt-in property that connects Syriac producer-side shaping to text output while preserving byte-stable defaults
`sfTibetanShaping`	Enables Tibetan GSUB shaping and synthetic-codepoint emission for shaped Tibetan glyph IDs
`sfMongolianShaping`	Enables Mongolian positional-form shaping through joining analysis and font GSUB lookups

Poznámky k použití

Tibetan používá průchody funkcí GSUB pro podřazené souhlásky a samohlásky. Syriac a Mongolian používají průchody třídami spojování a pozicemi k výběru forem init, medi, fina nebo isol definovaných písmem. AutoShapeSyriac a příznaky sfTibetanShaping/sfMongolianShaping propojují tyto pomocné metody s textovým výstupem
