Sonic Retro uses the UTF-8 character encoding for all pages. This allows the greatest flexibility for displaying international characters and other types of special symbols. In general, a wide range of characters is not absolutely necessary for this wiki's purposes, but the option for using additional characters provides greater flexibility for future expansion, for example in adding mathematical formulae and the like.
