Its purpose is to provide an implementation guideline for consumers of fonts (mainly software applications); it lists a variety of standard names that are given to glyphs that correspond to certain Unicode character sequences.
For producers of fonts, Adobe suggests a more limited set of names, the Adobe Glyph List for New Fonts (AGLFN), based on an earlier version of the AGL.
The Adobe Latin (AL) is a mapping of 1,307 (pre-composed) glyph names.
These character sets are informative, not normative, and some have changed since they were first issued.
For example, the original version of AL3 did not include the Turkish lira nor the ruble.
