The TT Rationalist typeface consists of 22 two styles: 10 upright, 10 real Italics and two variable fonts, each with over 950 glyphs. It supports over 200 languages and contains 27 OpenType features. In addition to the standard ones, there are Small Capitals for Latin and Cyrillic languages, alternative versions of the ampersand and the letter g. The italics have two stylistic sets allowing to switch the design of style-forming characters (k, v, w, y, z) between italic and classical forms.
