+When auto-escaping is in effect, all content derived from variables has HTML
+escaping applied before placing the result into the output (but after any
+filters are applied). This is equivalent to manually applying the
+:tfilter:`escape` filter to each variable.
+
+The only exceptions are variables already marked as "safe" from escaping.
+Variables could be marked as "safe" by the code which populated the variable,
+by applying the :tfilter:`safe` or :tfilter:`escape` filters, or because it's
+the result of a previous filter that marked the string as "safe".
+
+Within the scope of disabled auto-escaping, chaining filters, including
+:tfilter:`escape`, may cause unexpected (but documented) results such as the
+following:
+
+.. code-block:: html+django
+
+    {% autoescape off %}
+        {{ my_list|join:", "|escape }}
+    {% endautoescape %}
+
+The above code will output the joined elements of ``my_list`` unescaped. This
+is because the filter chaining sequence executes first :tfilter:`join` on
+``my_list`` (without applying escaping to each item since ``autoescape`` is
+``off``), marking the result as safe. Subsequently, this safe result will be
+fed to :tfilter:`escape` filter, which does not apply a second round of
+escaping.

+
+    As mentioned in the :ttag:`autoescape` section, when filters including
+    ``escape`` are chained together, it can result in unexpected outcomes if
+    preceding filters mark a potentially unsafe string as safe due to the lack
+    of escaping caused by :ttag:`autoescape` being ``off``.
+
+    In such cases, chaining ``escape`` would not reescape strings that have

 To escape each element of a sequence, use the :tfilter:`escapeseq` filter.
