of the Saffron Type System announced a representation for stroke-based fonts called Stylized Stroke Fonts (SSFs) with the aim of providing the expressiveness of traditional outline-based fonts and the small memory footprint of uniform-width stroke-based fonts (USFs). AutoCAD uses SHX/SHP fonts. Subsetting A typical font may contain hundreds or even thousands of glyphs, often representing characters from many different languages. Oftentimes, users may only need a small subset of the glyphs that are available to them. Subsetting is the process of removing unnecessary glyphs from a font file, usually with the goal of reducing file size. This is particularly important for web fonts, since reducing file size often means reducing page load time and server load. Alternatively, fonts may be issued in different files for different regions of the world, though with the spread of the OpenType format this is now increasingly uncommon.
