unescape

I use apache common lang to unescape a block of html text which contains &nbsp;,

I want to filter out blocks that contains only whitespaces. But I can't test the as a whitespace. It's not in the normal whitespace list(http://en.wikipedia.org/wiki/Whitespace_character), and I try to print its Hex form by calling Character.getNumericValue which return -1. &nbsp should be a whitespace,isn't? But How can I test it?
