How many glyphs can an OpenType format have?
65,000 glyphs
OpenType fonts may contain more than 65,000 glyphs, which allows a single font file to contain many nonstandard glyphs, such as old-style figures, true small capitals, fractions, swashes, superiors, inferiors, titling letters, contextual and stylistic alternates, and a full range of ligatures.
What is OpenType in Illustrator?
The OpenType panel lets you set up rules for using glyphs. For example, you can specify that you want to use ligatures, titling characters, and fractions in a given text block. Using the OpenType panel is easier than inserting glyphs one at a time and ensures a more consistent result.

How is the glyf data table used in OpenType?
Rather, the ‘loca’ table provides an array of offsets, indexed by glyph IDs, which provide the location of each glyph data block within the ‘glyf’ table. Note that the ‘glyf’ table must always be used in conjunction with the ‘loca’ and ‘maxp’ tables.
How is the total number of glyphs specified in glyf?
The total number of glyphs is specified by the numGlyphs field in the ‘maxp’ table. The ‘glyf’ table does not include any overall table header or records providing offsets to glyph data blocks. Rather, the ‘loca’ table provides an array of offsets, indexed by glyph IDs, which provide the location of each glyph data block within the ‘glyf’ table.
How is the size of a glyf data block determined?
The size of each glyph data block is inferred from the difference between two consecutive offsets in the ‘loca’ table (with one extra offset provided to give the size of the last glyph data block). As a result of the ‘loca’ format, glyph data blocks within the ‘glyf’ table must be in glyph ID order.
Where to set flags in the glyf data table?
If all glyphs are done like this, set bit 1 of flags field in the ‘head’ table. Note: The glyph descriptions do not include side bearing information.
