Breaking the 64K limit

• The next font format (OpenType 2?) should support > 64K glyphs in one font.
• GID will be 32-bit.
• A “subset” table would be present to support legacy APIs that expect GID being 16-bit. It is a bijection between 16-bit “Legacy GID” and 32-bit “Real GID”.
• Legacy API implementations should reject “OT2” fonts if the subset table is absent – which means this font is designed exclusively for new API.
• A STAT-like mechanism will be used to “break down” an “OT2” font into a family of legacy-API-aware fonts.
• When processing in legacy software…
  • TTF component references – if still supported – will reference to Real GID rather than Legacy GID.
• CMAP, GSUB, COLR, SVG entries involving glyphs outside the down-level subset will be ignored.

Assembly Alternatives Table ASMB

Assembly Alternatives Table (ASMB) defines the mechanism for complex justification, including Kashida. The principle is to associate assembly alternative lists to current glyphs. An assembly alternative list will have multiple glyph assemblies, being a glyph list with optional stretchable parts.

The table follows the structure of GSUB and GPOS. Listing lookups only.

Lookup type 1: Simple glue application

• subtableFormat: UInt16: Format identifier: format = 1
• coverage: Offset16 Coverage: Offset to Coverage table, from beginning of this subtable.
