title: unconverted data remains python strptime
body: <p>I am trying to convert strings to datetime in python, but I am getting an error "unconverted data remains: 11". The strings I am dealing with have a form like "Dec\xa031 2011". I think the unicode character is causing a problem. I have tried splitting on \xa0 which gives me ['Dec', '31 2011'], then joining. I have also tried replacing by re with re.sub('\xa0', '', dateStr). Neither has worked.</p>
