Intended for continuous reading on the web (longer articles in online news, magazines, blogs), Yrsa supports over 92 languages. A special consideration was given to Central and East European languages and proper shaping of their accents. A version that also supports 2 languages in the Gujarati script (Gujarati and Kachchi), is available as Rasa. In terms of glyphs included Rasa is a superset of Yrsa and includes the complete Latin, but in Rasa the Latin may be adjusted to support the primary Gujarati font.
It is a deliberate experiment in remixing existing typefaces: The Latin part began with Eben Sorkin's Merriweather. The Gujarati began with David Březina’s Skolar Gujarati.
