Paul,

I wonder how that encoding was changed. The LyX document I last worked on
has the Language default selected; the Other shows a grey-out Unicode
(utf8).

So, the MWE displays the bibliography but the main document still does not
after changing the Language to Unicode (utf8).

$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE=C
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

There's no latin9 here, either.

Here, the JabRef settings also specify UTF8 (see attached) so I've no idea
where LyX is seeing latin9.

Thanks,

Rich
