Abstract
Abstract A method of encoding a document with text characters includes the steps of providing a font memory with a first memory region for storing a plurality of basic unit information and a second memory region for storing a plurality of character information, and selecting a text character of the document. If the character information corresponding to the selected text character is found in the font memory, a corresponding user-defined code is assigned to the selected text character, and the corresponding user-defined code is stored in a character information region of a font file. The character information corresponding to the selected text character is stored in the character information region of the font file, and the basic unit information of the constituting basic units that constitute the selected text character is stored in a basic unit information region of the font file. If the character information corresponding to the selected text character is not found in the font memory, a corresponding user-defined code is assigned to the selected text character and is stored in the character information region of the font file, and outline data of the selected text character is generated and stored as character information of the selected text character in the font file.
