fonts-fantasque-sans font displays numeric codes

[Erik Zoltan]

As shown in the attached screenshot, the fantasque sans mono font displays hex codes in boxes rather than actual characters. In the photo, I'm using gedit. The first line of text says "The quick brown fox jumps over the lazy dog".

To produce this bug, I installed the font from the package repository and tried to use the font on my system. In addition to gedit, the problem occurs in Gnome Tweaks or anywhere else I try to look at the font. I have a dual boot KDE and GNOME Kubuntu system, but I'm running in GNOME only.

I tried uninstalling and reinstalling, but got the same issue. The issue affects all the fonts in the package, but none of the other fonts on my system.

Actually, the font typeface itself looks OK in the "Fonts" application, but it appears there are multiple copies of each version (e.g. multiple copies of Fantasque Sans Mono, Regular). I'm attaching another screenshot, because it looks pretty surprising.

I am experiencing the very same issue on a fresh installation of Kubuntu 21.04. fc-list shows that Fantasque Sans has been installed in multiple styles, stylistic sets and font formats:
