urllib2にいくつかのURLを開くことができませんが、まだブラウザで開くことができますか？

Question

urlをfirefoxやchromeで開くことはできますが、urllib2で開くことはできません。

>>> req = urllib2.Request(r"http://ratedata.gaincapital.com/2014/.\01 January", headers={'User-Agent' : "Mozilla/5.1"}) 
>>> urllib2.urlopen(req) 

Traceback (most recent call last): 
    File "<pyshell#134>", line 1, in <module> 
    urllib2.urlopen(req) 
    File "/usr/lib/python2.7/urllib2.py", line 127, in urlopen 
    return _opener.open(url, data, timeout) 
    File "/usr/lib/python2.7/urllib2.py", line 410, in open 
    response = meth(req, response) 
    File "/usr/lib/python2.7/urllib2.py", line 523, in http_response 
    'http', request, response, code, msg, hdrs) 
    File "/usr/lib/python2.7/urllib2.py", line 448, in error 
    return self._call_chain(*args) 
    File "/usr/lib/python2.7/urllib2.py", line 382, in _call_chain 
    result = func(*args) 
    File "/usr/lib/python2.7/urllib2.py", line 531, in http_error_default 
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) 
HTTPError: HTTP Error 400: Bad Request 

非常に奇妙なURLですが、これをどのように修正できますか？
