> 1. Introduction
>
> This document describes Adobe(R)'s PostScript(R) glyph naming
> conventions in the context of Unicode. The purpose of these conventions
> is to attach standardized semantics to glyph names, including glyphs
> that represent characters that don't have standard Unicode values (UVs)
> like certain ligatures or glyphic variants.
>
> Two perspectives are presented: that of the font developer, when
> deciding what to name the glyphs in a font; and that of any process that
> needs to extract Unicode semantics from glyph names, such as a Type
> 1-to-OpenType converter when creating a Unicode 'cmap', or the search
> facility in an application that does not use OpenType layout tables.
>
> The 3 data files referred to in this document are:
>
> * "The Adobe Glyph List" (AGL). This maps approximately 1000 glyph names
> to standard or Corporate Use subarea (CUS) UVs. For more details,
> including double-mapped glyphs and industry standard character sets
> covered by the list, see section 4.
>
> * "Unicode's Corporate Use Subarea as used by Adobe." These assignments
> cover characters such as small capitals which are commonly used in
> Adobe fonts but are not part of the Unicode Standard. This data file
> also provides Unicode-style character decompositions for many of these
> assignments. For more details, see section 4.b.
>
> * "Zapf Dingbats Glyph Names and UVs." This list should be used only for
> the font Zapf Dingbats, as described in section 3.a.
>
> The Unicode Standard 2.1 has been used in this document and related data
> files, except for the 4 characters mentioned in the header of the AGL
> data file.
