API	Usage notes
`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

Usage notes

Tibetanski zapis uporablja prehode funkcij GSUB za podložene soglasnike in samoglasnike. Sirščina in mongolščina uporabljata sprehajalce razredov vezave in položajev za izbiro z pisavo določenih oblik init, medi, fina ali isol. AutoShapeSyriac in zastavice sfTibetanShaping/sfMongolianShaping povežejo te pomočnike z izpisom besedila
