Description Ryosuke Niwa 2013-08-16 10:19:40 PDT 
While
var value = '' + attributedString.getAttributeValueAtIndex(attributeNames[j], location);
results in value containing useful description string like:
"Times-Roman 16.00 pt. P [] (0x7f889c3225e0) fobj=0x7f889c322240, spc=4.00"

var value = attributedString.getAttributeValueAtIndex(attributeNames[j], location).toString()
results in value containing:
[object ObjCRuntimeObject]
