      <doc xml:space="preserve">`PangoFcDecoder` is a virtual base class that implementations will
inherit from.

It's the interface that is used to define a custom encoding for a font.
These objects are created in your code from a function callback that was
originally registered with [method@PangoFc.FontMap.add_decoder_find_func].
Pango requires information about the supported charset for a font as well
as the individual character to glyph conversions. Pango gets that
information via the #get_charset and #get_glyph callbacks into your
object implementation.</doc>
