Comment 14 for bug 50529

Scott Ritchie: there were al kinds of problems with ugly fonts being filled in into the Tahoma-Bold font, e.g. in web browsers, creating ugly pages. The problem is that installing a font will have a system wide impact, so you can't package it just for Steam and not use it in e.g. Firefox.

A separate package could be possible but it's still quite a hack. The problems with the webpages would resurface on systems where you would install that package.
Is there no way to fix Steam?
