Why do svg fonts always crash even if they are set in css?

Question

HTML

Constantly when I create an svg image for a logo and there is a third-party font, for example Open Sans, then the font on the site flies to the default one (in Windows it's Time New Romans mine). The fonts are connected in the head tag and in the styles to the body but there is no sense (what to do?

Answer 1

Convert the font in the logo to curves.
