Description
I'm using Racket 8.1 from the Ubuntu PPA with Ubuntu 20.04.
Some text in the UI is shown entirely as hex codes, e.g. in the REPL; see the screenshot (the same also applies to the Help→About DrRacket dialog).
I ran drracket with no ~/.racket directory, to avoid any problem caused by my settings.
I feel I'm missing something obvious…I have my Interface Text font set to Cantarell Regular (GNOME default), which is working fine, my Monospace Text font set to Source Code Pro Medium, which seems to be working too, and my Document Text font set to Noto Sans Regular, which should work fine (I tried changing it to Cantarell, but to no avail).

Research direction
Start by reproducing the rendering problem with drracket in the REPL and in the Help→About DrRacket dialog on Ubuntu 20.04, using a clean ~/.racket directory and the stated fonts. The payload names no source file or test; done means the affected UI text renders as readable characters rather than hexadecimal blocks.
