Its fonts are designed in a monolinear, geometric sanserif style.
Like several early geometric sans typefaces from the last century, Biryani’s characters have a strong flavor to them; they are more wonky than sterile.
Biryani’s fonts are indeed meant for text, just not necessarily for very long, immersive reading-length passages.
Currently, the Biryani fonts support the Latin and Devangari scripts, meaning that Indian languages like Hindi, Marathi, and Nepali may be set with the fonts, in addition to most Western and Central European languages.
