+Subject: [PATCH] Add support for GNU Libidn2
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Patch by Robert Scheck <robert@fedoraproject.org> for elinks >= 0.12 which replaces current
+GNU Libidn support (IDNA 2003) by GNU Libidn2 support (IDNA 2008). This is e.g. allowing
+the 'ß' character in domain names. See also the Red Hat Bugzilla #1098789 for some further
+information: https://bugzilla.redhat.com/show_bug.cgi?id=1098789
