Within a font, each included glyph is managed by its glyph name. In the case of CID-keyed fonts, such as Adobe-Japan1 fonts, the CID serves as the glyph name. On the other hand, fonts that do not have CIDs assigned to them (name-keyed fonts), such as Latin fonts, have string-based names assigned to each glyph. For example, “A” is “A,” “a” is “a,” and “1” is “one.”

The Adobe Glyph List Specification serves as an indicator for glyph names in name-keyed fonts. This specification refers to the Adobe Glyph List for New Fonts (AGLFN) as a list of recommended glyph names for use in new fonts. “A,” “a,” and “one” are all glyph names defined in AGLFN.

For glyphs not defined in AGLFN, it is standard practice to use their Unicode code point as the glyph name, provided that the code point is associated with the glyph. For example, if the hexadecimal value of a Unicode code point is 021B, the glyph name is “uni021B” or “u021B.”
