How/why does dired screw up the buffer-file-coding-system used for
reading test.txt?
AFAICT it doesn't modify buffer-file-coding-system-for-read, the
default value of buffer-file-coding-system, file-coding-system-alist,
find-file-hooks, insert-file-contents-pre-hook,
insert-file-contents-post-hook, ... What am I missing?
I think there are some lurking bugs. I tried doing some stuff with custom
coding systems and it didn't work at all.
