"""
There are several types of simple fonts, all of which have these properties:

•   Glyphs in the font shall be selected by single-byte character codes obtained from a string that is shown by
    the text-showing operators. Logically, these codes index into a table of 256 glyphs; the mapping from
    codes to glyphs is called the font’s encoding. Under some circumstances, the encoding may be altered by
    means described in 9.6.6, "Character Encoding".

•   Each glyph shall have a single set of metrics, including a horizontal displacement or width, as described in
    9.2.4, "Glyph Positioning and Metrics"; that is, simple fonts support only horizontal writing mode.

•   Except for Type 0 fonts, Type 3 fonts in non-Tagged PDF documents, and certain standard Type 1 fonts,
    every font dictionary shall contain a subsidiary dictionary, the font descriptor, containing font-wide metrics
    and other attributes of the font; see 9.8, "Font Descriptors". Among those attributes is an optional font file
    stream containing the font program.
