FoxyCart XML Datafeed issue

[eluser]cwillenbrock[/eluser]
After a little more digging into the differences, I've noticed that any character of % 0 0 to % 2 0 (but without the spaces) with the exception of % 0 9 gets removed from the string which is what's causing the corruption.

So I now I know WHAT is causing the corruption, but I don't know what's causing the string to get affected.

Again, any ideas?
