Glyph

A single designed unit within a
Font
, representing a character,
Ligature
, diacritical combination, or symbol. A glyph is the specific drawn form — as distinct from the abstract character it encodes. A single character (such as the lowercase a) may be represented by multiple glyphs (e.g., a single-story and a double-story variant), and a single glyph (such as an fi ligature) may represent more than one character.
