Version of Roboto Light bundled with Engine has an issue with Cyrillic character.

I’ve took a look on the font and it’s dated by 2011. In newer version this issue is fixed.

Is it only the Light font that’s affected by this?

Seems so. Since I see no other Light fonts there.

Thanks for the report. I’ve updated the Roboto Light font we use to the version from Google Fonts, and this will go out in 4.19.
