+If you get a UnicodeEncodeError
+===============================
+
+If you're taking advantage of the internationalization features of Django (see
+:ref:`topics-i18n`) and you intend to allow users to upload files, you must
+ensure that the environment used to start Apache is configured to accept
+non-ASCII file names. If your environment is not correctly configured, you
+will trigger ``UnicodeEncodeError`` exceptions when calling functions like
+``os.path()`` on filenames that contain non-ASCII characters.
+
+To avoid these problems, the environment used to start Apache should contain
+settings analogous to the following::
+
+    export LANG='en_US.UTF-8'
+    export LC_ALL='en_US.UTF-8'
+
+Consult the documentation for your operating system for the appropriate syntax
+and location to put these configuration items; ``/etc/apache2/envvars`` is a
+common location on Unix platforms. Once you have added these statements
+to your environment, restart Apache.
