In order to default to a more secure character encoding,
Zend_Filter_HtmlEntities now defaults to UTF-8
instead of ISO-8859-1.
Additionally, because the actual mechanism is dealing with character encodings and not
character sets, two new methods have been added,
getEncoding(). The previous methods
setCharSet() are now
deprecated and proxy to the new methods. Finally, instead of using the protected members
directly within the
filter() method, these members are
retrieved by their explicit accessors. If you were extending the filter in the past,
please check your code and unit tests to ensure everything still continues to work.
