Encoding Error in PHP Generated XML File

[kez10]

I have generated an XML file in PHP using the DOMDocument class, the data was grabbed from a MySQL database. A lot of the data contains HTML markup, but I've encased all of it in a CDATA section.At first the file had a lot of encoding errors, but running everything through utf8_encode() before putting it into the file seems to have fixed all the errors except one.Here is the error I have right now:\[code\] error on line 5113 at column 450: Input is not proper UTF-8, indicate encoding ! Bytes: 0x14 0x31 0x30 0x30\[/code\]I found some posts on here with similar errors, but none have solved my problem, or suggest using utf_encode(). Here is the section that seems to be triggering the error:\[code\] ...quiet portable package. ]]></Summary><Features><![CDATA[The EF4500iSE was designed for maximum fuel...\[/code\]The error seem to be between CDATA[ and The, although I can't see any characters between there and that piece is the same as every other CDATA block in the file. If I remove the entire Features element and it's contents, the file loads up fine.Here is the link to the file: http://test.hhdev.hothousemarketing.com/inventory.xml
