The error is triggered when the edit command writes the string to a
temporary file using the builtin open function. The codecs.open
function will write a non-ascii character to a file as the following
shows.

Python 2.5.1 (r251:54863, May  2 2007, 16:56:35)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> s = u'\245\200'
>>> open('test.uraw', 'w').write(s)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position
0-1: ordinal not in range(128)
>>> import codecs
>>> codecs.open('test.uraw', 'w',encoding='utf-8').write(s)
>>>
