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. If you want a standard character set (extended ASCII like ISO 8859-X), then please specify. ISO sets defined. If we do not offer the characters you need, please contact us 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 full 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.
