Downloadable fonts are rendered from True Type or Open Type Windows fonts and then stored in .SIF files. One file for each font type, size, attribute (i.e., italic, bold), and character subset included. Please specify if you want a standard character set (extended ASCII like ISO 8859-X). ISO sets defined. If we do not offer the characters you need, please don’t hesitate to contact our technical support team and specify the Unicode subset you need.
We support UTF-8 encoding. Find UTF-8 for a given Unicode. For Unicode, the subset size determines the size of the .SIF font. The complete Unicode set of a font like SimSun at 16 pixels high (not 16-point) is 946KB and has over 20,000 characters. See Fonts for Embedded Touch Screen Development for a comprehensive explanation of working with fonts.
