I have problem with displaying the data in DHTMLX Grid XML

I am using the DHTMLX in CI with the Oracle in the backend . Whenever i insert the unicode character following Error is shown . I have tried by changing the set_encoding to utf-8 but didnot work.
Please Help ME

My Error:

<?xml version='1.0' encoding='UTF-8' ?><![CDATA[[Acccess] [Module] [Link Test ]]]>

<![CDATA[[Acccess] [Module] [Link Test ]]]>

Please try to load the datafeed directly in browser.
Parser will show more detailed error description, most probably - data is not really in UTF-8

Unfortunately the issue cannot be reconstructed locally.
Please, make sure that you have configured the encoding correctly on your server in your html and in your browser.
Also, please, make sure that your problematic characters in UTF-8 encoding.
If issue still occurs - please, provide a problematic xml file or a demo link to your project where the issue can be reconstructed.

I am newbie to dhtmlx , so please can you please tell me how to load the datafeed directly into the browser.

Please, try to paste the link to your datafeed directly in the browser’s address bar.
