Non-breaking space ( ) should be preserved on rendering

>>> import CommonMark as commonmark
>>> parser = commonmark.DocParser()
>>> renderer = commonmark.HTMLRenderer()
>>> renderer.render(parser.parse("big   space"))
'<p>big   space</p>\n'
>>> expected = '<p>big \u00A0 space</p>\n'

The CommonMark spec shows an example of   being replaced by something other than a normal space (presumably a Unicode non-breaking space character).

From a doc that the spec links to:

  " ": { "codepoints": [160], "characters": "\u00A0" },
  "&nbsp": { "codepoints": [160], "characters": "\u00A0" },

My example showed that the renderer translates it to a normal space, not \u00A0. I think this is a bug in CommonMark

I can confirm this bug. The spaces are all ord(u' ') == 32 while ord(u"\u00A0") == 160.
