Definicja rich text

Result of adding additional information to Plain Text Examples of information that can be added: font data, visual appearance, e.g., color, formatting information, phonetic annotations, interlinear text, etc.

Unicode does not address the representation of rich text. It is expectedthat systems and applications will implement proprietary forms of rich text. Some public forms of rich text are available, e.g., ODA, SGML, XML, etc. Removing all of the additional information in the rich text should leave only plain text remaining.
