+/**
+ *  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)
