Because of the *other* fields: I believe you wrote the #1 gem of JtR -
single mode! For example, if you try to use single mode on a pwdump file
with user names like Администратор, Möller and Anaïs, you will have a
great deal better chance of cracking them if JtR knows what encoding
that file is in. Besides, nowadays dang near *everything* is UTF-8 so
the warning is a good thing - in this case it was a (albeit vague to the
user) indication that the OP did something wrong.

I'm really curious how you somehow do not think that should be a fatal
error? Before I added it (IIRC) you could run a perfectly fine wordlist
encoded in UTF-16 and just not get a single crack, with NO clue as of
why, even though *all the right words were there*. Now THAT is a problem
if you ask me.
If you mean we should actually support that dreadful encoding, sure.
Just open an issue. I think all the needed bits are in there so it
should be fairly trivial.
Cheers,
