The OpenType format allows you to define a glyph’s type. This can be one
of the following values:
Unassigned
Glyph type is not defined
Simple Single character
Ligature
Multiple characters
Mark
Non-spacing glyph used as a mark
Component
Part of a character
Glyph type is used in a lookup when you need to limit it to the glyphs of a
particular type using the lookupflag command (page 644).
You define the glyph type using the glyph properties panel. Select one or
more glyphs in the Font window and open the panel with the Edit >
Properties command:
Select the glyph class in the list to the right of the icon. If multiple
glyphs were selected, the new type will be assigned to all of them.
