Sylfaen is a multi-script serif font family designed by John Hudson and W. Ross Mills of Tiro Typeworks, and Geraldine Wade of Monotype Typography.
[1] In 1997, Tiro was hired by Microsoft Typography to consult on the production of support materials for OpenType font development.
Part of this project was producing a multi-script font used for displaying glyphs in Microsoft's cancelled Web Resource for International Typography (WRIT) database, which was a tool for establishing character and glyph requirements for given languages, geographical areas or scripts (or combinations thereof).
The project included support for Latin, IPA, Cyrillic, Greek, Armenian, Georgian, and Ge'ez (Ethiopian) characters.
Latin glyphs were designed by John Hudson, and the first script developed for Sylfaen.
