unreadable system font

[Ermudu54]

Hi,
I'm having a weird problem: The system font has become unreadable. See screenshot.
Each letter is replaced by the same shape that imitates handwriting.

OS Elementary (I don't know witch one, and can't read it now !)
Did I accidentally change a setting? (I fell asleep in front of my screen yesterday)
Is it malware?
Do you have an explanation?
Thank's

What you are seeing is the special font used to obscure text in e.g. screenshots. Not obvious how this could accidentally become the desktop font though. You could try using dconf-editor or the command line to look at the org/gnome/desktop/interface/font-name setting and reset it to the default.

The command to reset the system font is gsettings reset org.gnome.desktop.interface font-name

Oh, thank you very much !!!!
With the dconf editor I was unable to read something ... due to my problem ;-).
Your command save me ! Je vous remercie beaucoup.

I don't know how the problem came, but yesterday I took screenshots.

Glad to help. If it happens again then consider raising a bug report (especially if it is reproducible).
