Endurance Pro™ Regular was designed by Steve Matteson to fill the need for a more elegant, less industrial-looking neo-grotesque sans serif design.ÿ The name Endurance lends itself to the fact that the typeface was designed to work well under extreme conditions from billboards to mobile phone screens. Endurance Pro™ Regular was designed with on-screen legibility as a key attribute, and with careful detailing for a more refined appearance in large sizes. Endurance Pro Regular has an extensive character set with WGL support (Greek, Cyrillic and Eastern European characters) to meet the needs of multinational companies and creative professionals who desire OpenType's typographic features (with old style figures, proportional figures, fractions, superiors and a slash zero). Character Set: Latin-1, WGL Pan-European (Eastern Europe, Cyrillic, Greek and Turkish).
