Hey there,

so that textwrap.wrap() breks non-breaking spaces, is this a bug or
intended behavior? For example:

Python 3.4.0 (default, Apr 11 2014, 13:05:11)
[GCC 4.8.2] on linux

>>> import textwrap
>>> for line in textwrap.wrap("foo dont\xa0break " * 20): print(line)
...
foo dont break foo dont break foo dont break foo dont break foo dont
break foo dont break foo dont break foo dont break foo dont break foo
dont break foo dont break foo dont break foo dont break foo dont break
foo dont break foo dont break foo dont break foo dont break foo dont
break foo dont break

Apparently it does recognize that \xa0 is a kind of space, but it thinks
it can break any space. The point of \xa0 being exactly to avoid this
kind of thing.

Any remedy or ideas?

Cheers,
Johannes
