-Subject: [PATCH] Fail parsing early on if encoding conversion failed
-
-For https://bugzilla.gnome.org/show_bug.cgi?id=751631
-
-If we fail conversing the current input stream while
-processing the encoding declaration of the XMLDecl
-then it's safer to just abort there and not try to
-report further errors.
