/**
 * this class represents the flow object 'fo:character'. Its use is defined by
 * the spec: "The fo:character flow object represents a character that is mapped to
 * a glyph for presentation. It is an atomic unit to the formatter.
 * When the result tree is interpreted as a tree of formatting objects,
 * a character in the result tree is treated as if it were an empty
 * element of type fo:character with a character attribute
 * equal to the Unicode representation of the character.
 * The semantics of an "auto" value for character properties, which is
 * typically their initial value,  are based on the Unicode codepoint.
 * Overrides may be specified in an implementation-specific manner." (6.6.3)
