 Marks a string as not requiring further HTML escaping prior to output. When
 autoescaping is off, this filter has no effect.
 
+.. note::
+
+    If you are chaining filters, a filter applied after ``safe`` can
+    make the contents unsafe again. For example, the following code
+    prints the variable as is, unescaped:
+
+    .. code-block:: html+django
+
+        {{ var|safe|escape }}

 .. templatefilter:: safeseq
