Abstract
The method of the invention allows both single-byte character set (SBCS) and double-byte character set (DBCS) fonts in a DBCS code page. The invention stores the SBCS and DBCS text of the document in separate areas. Each area contains the following specific information about the text: the actual text itself, the length in bytes of the text, the horizontal starting position of the text, the font attributes for that text, a flag to indicate that the text is SBCS or DBCS text, and the value which points to the next area containing some text. The font attributes contain information such as the font typeface name, point size, color, weight, width, and the value to indicate whether the font type is an SBCS or a DBCS font type. A document is then set up to use different fonts, SBCS or DBCS, for specific sections of text and alternating back and forth between the fonts as many times as is necessary. The text of the document that uses the different fonts will be in separate areas and each area will contain its own text and font specific information.
