In RHEL 10 (and other modern systemd-based distributions), the hostnamectl command has been updated to include visual icons using UTF-8 characters for the Chassis field. This change is part of the upstream systemd project's effort to make the CLI output more visually informative for users. Instead of just seeing the word "laptop" or "server," you now see a corresponding symbol. This leads to following: ``` warning: JSON.generate: UTF-8 string passed as BINARY, this will raise an encoding error in json 3.0 ``` Signed-off-by: Joseph J Nuspl Jr <nuspl@nvwls.com>

There was a problem hiding this comment.
This looks great, thanks.
I will say, I think we should extend the tests to have the emoji tested in places other than just the end of the line, but since that's where they are today, I'm not gonna block on that.
I've requested the tests unblocked, and then we'll merge.
