Re: encode/decodeXMLEntities

OK...I was being stupid...however...because I'm stupid...I was unaware of ANOTHER problem... Let's take the following codes: €�‚ƒ„…†‡ˆ‰Š‹Œ�Ž��‘’“”•–—˜™š›œ�žŸ ¡¢£¤¥¦§¨©ª«¬­®¯°±²³´µ¶·¸¹º»¼½¾¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüý Because I've got mbstring turned on...and the internal PHP encoding set for UTF-8...these characters are encoded to their UTF-8 equivalents...eg..there is no single ASCII code equivelent or direct map in the UTF-8 character set.. What does this mean... we'll, the $encoder array below which loads characters chr(192), chr(193), etc. needs to have the UNICODE characters...not these ASCII characters...and the text sent in the $xml variable needs to be UNICODE, not ascii....and, it will be unicode if all is done right and mbstring's encoding is all unicode. However, this makes the encodeXMLEntities a little more difficult as the CHARACTERS that are in the array to match to must be in the Backend Encoding format. Perhaps everything should be run through as unicode and the encoding format be translated to unicode for this replacement. James Barwick wrote:

This code should be implemented in XML/Tree/Node.php as soon as possible so that we can all work with UTF8!!!! Any critisism? Feedback? I hope the PEAR developers are reading this...perhaps an email directly to Christian will help.... James James Barwick wrote:
