"""
In PDF, a font is classified as either nonsymbolic or symbolic according to whether all of its characters are
members of the standard Latin character set; see D.2, “Latin Character Set and Encodings”. This shall be
indicated by flags in the font descriptor; see 9.8.2, "Font Descriptor Flags". Symbolic fonts contain other
character sets, to which the encodings mentioned previously ordinarily do not apply. Such font programs have
built-in encodings that are usually unique to each font. The standard 14 fonts include two symbolic fonts,
Symbol and ZapfDingbats, whose encodings and character sets are documented in Annex D.
