What font does Figma substitute by default?

Question

Design

Hello
There are 4 different fonts on the screen, all do not support Cyrillic. English characters in their own font, and Russian characters in an incomprehensible one. Figma itself substitutes some kind of its own font for Russian. How to understand which one? When selected, it still shows the name of the font that I chose, but in fact, in Russian characters, this is not it.

Answer 1

I found. Figma substitutes Open Sans

Answer 2

What makes you think that figma substitutes fonts? Most likely, this is done by the browser, using either the font set in it by default, or a font of a similar family with the presence of the necessary characters.
