+ * #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
+ * pango_fc_font_map_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.
+ *
+ * Since: 1.6
