Issue2772

On Jython no-break space (u'\xa0'), figure space (u'\u2007̈́) and narrow no-break space (u'\u202F') are not considered to be space characters. Other space characters listed at https://www.compart.com/en/unicode/category/Zs are.

This affects also string methods like `strip()` and `split()`, but the `re` module doesn't seem to be affected.

I'm happy to report that this works in the development tip, thanks to: https://hg.python.org/jython/rev/a1f68d091a1c .

Awesome, thanks Jeff!
