## Python 2.7 and UCS

Note, to get this working on python 2.7, you must have python built with _UCS4_ via
`--enable-unicode=ucs4`. You can test for UCS4 with:

```{code-block} python

>>> import sys
>>> sys.maxunicode > 0xffff
True

```

Most packaged and included python distributions will already be build with UCS4 (such as Ubuntu's
system python). On python 3.3 and greater, this distinction no longer exists, no action is needed.
