+Active Support's version also considers Unicode spaces.  For example, `"\u2000\u2001\u2002\u2003\u2004\u2005\u2006\u2007\u2008\u2009\u200A\u202F\u205F\u3000".blank?` is true in Active Support even though `fast_blank` would treat it as *not* blank.  Therefore, `fast_blank` also provides `blank_as?` which is a 100%-compatible Active Support `blank?` replacement.
