Anicesoft EPUB Converter: About RTF Format






The Rich Text Format (often abbreviated RTF) is a proprietary[6][7][8] document file format with published specification developed by Microsoft Corporation since 1987 for Microsoft products and for cross-platform document interchange.[citation needed]
Most word processors are able to read and write some versions of RTF.[9] There are several different revisions of RTF specification and portability of files will depend on what version of RTF is being used.[7][10] RTF specifications are changed and published with major Microsoft Word and Office versions.
It should not be confused with enriched text (mimetype “text/enriched” of RFC 1896) or its predecessor Rich Text (mimetype “text/richtext” of RFC 1341 and 1521); nor with IBM’s RFT-DCA (Revisable Format Text-Document Content Architecture) which are completely different specifications.

A standard RTF file can consist of only 7-bit ASCII characters, but can encode characters beyond ASCII by escape sequences.[27] The character escapes are of two types: code page escapes and, starting with RTF 1.5, Unicode escapes. In a code page escape, two hexadecimal digits following a backslash and typewriter apostrophe are used for denoting a character taken from a Windows code page. For example, if the code page is set to Windows-1256, the sequence \’c8 will encode the Arabic letter bāʼ (ب).

Unlike many word processing formats, concise RTF code can be made human-readable. When an RTF file is viewed as a plain text file, characters within ASCII are legible and the markup language (formatting) elements not too distracting or counter-intuitive. However, the RTF files produced by most programs, such as Microsoft Word (MS Word), will contain such a large number of control codes that most files will easily be an order of magnitude larger than the corresponding plain text and very difficult to read.[28][29] Formats such as MS Word’s .doc are, in contrast, binary formats with only a few scraps of legible text.
