Developers are interested in improving their website performance. While font files are usually quite small in size—compared to, for example, images—and should only be a minor concern, font users are still tempted to reduce font file sizes to a minimum. There are several ways to save a few extra bytes, like removing glyphs and seemingly irrelevant OpenType features. However, altering font files will almost always violate licence agreements between foundries and users. This presentation will demonstrate *why* font makers are fussy about allowing users to tamper with their fonts by illustrating the importance of OpenType features for fonts with complex script support.
