Package: fonts-urw-base35 Version: 20200910-7 This is fixed upstream in https://github.com/ArtifexSoftware/urw-base35-fonts/pull/46. Quoting from that report:
The D050000L font was marked as an alias for "fantasy" but shouldn't be. As a result, if another "fantasy" font isn't installed with a higher priority, D050000L is used by some browsers (in my case Firefox, but not Chromium) when a fantasy font is requested. This results in unreadable text.
