Scheduller Month print problem

When I try to print the month view, I receibe the error:
SimpleXMLElement::__construct() [simplexmlelement.–construct]: Entity: line 3: parser error : Input is not proper UTF-8, indicate encoding ! Bytes: 0xE7 0x61 0x5D 0x5D

error report xml:

The page with scheduler, which encoding it is using?
Server side was built to work with unicode data, so if you are using different one - it may cause a problem.

In dhtmlxscheduler_pdf.js you can locate

var xml = "<data profile=’

and replace with

var xml = "<?xml version='1.0' encoding='iso-8859-1' ?><data profile=’

or any other encoding value ( it is not necessary if you are using unicode )

OK, fixed.
