Works fine for me - just what I needed! (Trying to get rid of pesky '&'s from a website, input by users, so that the HTML will pass validation...)

While the unicode and decimal value are in the range of the current W3C values. No checking is done to ensure that a named entity (alphanumerics) maps to a known entity name.
