Subject: [PATCH] =?UTF-8?q?fix(strings):=20transliterate=20=C3=9F,=20?=
 =?UTF-8?q?=C3=A6,=20=C3=B8=20and=20=C5=81=20in=20slugify?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

slugify relied on NFKD + ASCII encoding, which deletes letters that
have no decomposition, so "Ærøskøbing" became "rskbing" and
"Straße" "strae". Run the text through deburr first, which maps
these letters.

 ----------
 
+- Transliterate letters like ``ß``, ``æ``, ``ø`` and ``Ł`` in ``slugify`` through ``deburr`` instead of
+  dropping them.
 - Stop ``partial`` and ``partial_right`` wrappers from accepting a positional iteratee argument in
   a slot that a keyword argument already binds, so ``map_`` passes the element instead of an index
   into the bound parameter.
