The change is no longer local, which prompted some off-list comments
from Stefan that confused me.

mailcap-view-mime already binds coding-system-for-write to 'binary
before writing to a file and spawning a subshell, so why does the
coding-system-for-write matter in its caller eww-display-pdf?

In other words, can we remove the binding altogether from
eww-display-pdf and make the *eww pdf* buffer unibyte, as Stefan
suggested?

Could something funny happen / be happening during insertion from one
buffer into the other in eww-display-pdf?

Thanks,
