[BUG] Invalid non-UTF8 @data passed as text to web_socket_connection_send() on Cockpit

What steps will reproduce the bug?

open Cockpit on a web browser
Go to "terminal" tab
Use bat to open a file

What happens?

Nothing is displayed, and journalctl shows:

invalid non-UTF8 @data passed as text to web_socket_connection_send()

Even more strange: using bat with cat <file> | bat just works!

What did you expect to happen instead?

bat should display the file as usual

How did you install bat?
