CJKwrap is a library for wrapping and filling CJK text.
CJKwrap fix the issue24665 because Python 2 will stay broken forever: https://bugs.python.org/issue24665.
CJKwrap support both Python 2 (2.6 and above) and Python 3 (3.3 and above).
CJKwrap is developed by Florent Gallaire f@gallai.re.

To install the last stable version from PyPI::
$ sudo pip install cjkwrap
To install the development version from GitHub::
$ git clone https://github.com/fgallaire/cjkwrap
$ cd cjkwrap
$ sudo python setup.py install
Or you can just use the cjkwrap.py file alone, nothing more needed!
is_wide() to know if a char is double-width, cjklen() and cjkslices() to replace built-in len() and slicing::
>>> import cjkwrap
>>> cjkwrap.is_wide(u"c")
False
>>> cjkwrap.is_wide(u"長")
True
>>> cjkwrap.cjklen(u"最終的には良い長さ")
18
>>> head, tail = cjkwrap.cjkslices(u"最終的には良い長さ", 6)
>>> print(head)
最終的
>>> print(tail)
には良い長さ
As cjklen() uses len() for non unicode stuff, you can safely do this::
>>> from cjkwrap import cjklen as len
>>> len(u"最終的には良い長さ")
18
>>> len([1, 2, 3, 4])

wrap() and fill() to replace the ones from the Python standard library::
>>> wrapped_cjk = cjkwrap.wrap(u"最終的に良いラッピング", 10)
>>> for line in wrapped_cjk: print(line)
...

Mixed content is allowed::

>>> print(cjkwrap.fill(u"CJK 最終的には良い長さ", 10))
