No, I don't think so. Anyway, this is a tangent; if you think
everything is okay with the site, I can fetch files regardless.

How exactly did you do that? where was Emacs running and where was the
display running? Was that with or without X forwarding?
Also, this is the second file; what about the first one? Do you see
on Ubuntu problems with deleting characters in it, and if so, which
characters and what problems this causes?

To display RTL text on a terminal, you need to turn off bidirectional
features of the terminal, if it has them, because Emacs performs the
bidirectional processing by itself.

Sorry, I wouldn't know what to write there, and cannot present any
data as I don't have Kitty installed. I think it's better that you do
it.
