+Files
+=====
+
+If you intend to allow users to upload files, you must ensure that the
+environment used to run Django is configured to work with non-ASCII file names.
+If your environment isn't configured correctly, you'll encounter
+``UnicodeEncodeError`` exceptions when saving files with file names that
+contain non-ASCII characters.
+
+Filesystem support for UTF-8 file names varies and might depend on the
+environment. Check your current configuration in an interactive Python shell by
+running::
+
+    import sys
+    sys.getfilesystemencoding()
+
+This should output "UTF-8".
+
+The ``LANG`` environment variable is responsible for setting the expected
+encoding on Unix platforms. Consult the documentation for your operating system
+and application server for the appropriate syntax and location to set this
+variable.
+
+In your development environment, you might need to add a setting to your
+``~.bashrc`` analogous to:::

+    export LANG="en_US.UTF-8"
