Re: encode/decodeXMLEntities

It appears that there is a substr() problem with mb_substr() in PHP v4.3.1 Perhaps it's fixed in 4.3.4... if you create a string such as: $text="ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüý"; then substr($text,0,1) returns garbage.. Well, I guess I need to find the mbstring development and support forum!! Cheers So...if you plan to use these characters (which I do!!!) with mbstring turned on...then you will need another method to get encodeXMLEntities to work. James 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:
