+Date: Thu, 8 Apr 2021 19:43:43 +0200
+Subject: [PATCH] Remove dependency on unicode_util_compat
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Newer erlang versions, and this includes all dev-lang/erlang version
+currently in ::gentoo, do not require unicode_util_compat.
+
+This is based on
+https://github.com/benoitc/erlang-idna/pull/31/. Holger Weiß suggested
+to additionaly patch unicode_util_compat out of
+src/idna.app.src. Thanks Holger. :)
