Radiant CT supports 123 different languages such as Spanish, English, Portuguese, Russian, German and French in Latin and Cyrillic scripts. (Please note that not all languages are available for all formats.)
My first commissioned work was to digitize Radiant Bold Extra Condensed (originally designed by Robert Middleton in 1940) for use in the Sunday supplement to the San Francisco Examiner. I later created Light and Medium weights to match. The CastleType version of Radiant has a softer look than others available, and is the only one that includes the Cyrillic alphabet.
