Some emails show a message body that's nothing but / separated groups of ASCII characters, as for example "FJ/OHS/U7R/R3A/NT4/R03/0QY/T1N/VRC/WJ3/J6E/YXK/I6K/WNA..." continued for several pages.

Is this something that Thunderbird is doing, or is the gibberish the actual message? I've only bee using Thunderbird for a few months, and don't recall seeing anything like it with my previous email program (Opera). I'm using version 115.7.0 (64-bit) on OpenSUSE Linux.
