What is Identity h encoding?

CIDs are fonts whose glyphs have no names but are described in relation to a character collection. Thus it is a somewhat peculiar font encoding: instead of using glyph names as its basis, as do the Type 1 font encodings, it uses CID—i.e., the glyph numbers in a given character collection.
