Two comments:

If tests require an UTF-8 locale, I think the tests (maybe in 
build-aux/test-driver.scm?) should check that an UTF-8 that an UTF-8 
locale is actually in use and otherwise bail out properly.

It's not a file-name but rather the contents of the news file, so I 
would think we are just forgetting to pass some arguments like 
#:encoding "UTF-8" -- making the interpretation of the news file depend 
on the current locale doesn't seem good to me (it's encoding on stdout 
with "guix pull --news" is another matter).

Greetings,
