Hello.

I received this from the Debian bug system:

Subject: Bug#763820: gettext: msgunfmt aborts on incomplete UTF-8 character
Date: Thu, 2 Oct 2014 23:31:33 +0200
From: Jakub Wilk <address@hidden>

Package: gettext
Version: 0.19.2-2
Severity: minor
Usertags: afl

msgunfmt aborts when trying to print some strings containing incomplete
UTF-8 characters:

$ msgfmt invalid-utf8.po -o invalid-utf8.mo
$ msgunfmt invalid-utf8.mo
msgid ""
msgstr "Content-Type: text/plain; charset=UTF-8\n"

msgid "x"
Aborted

I would expect that the incomplete character is ignored (with the usual
"invalid multibyte sequence" warning); or at least that a reason for
aborting is given.
