Whether it is possible dhtmlxTree in names item (in most dhtmlxTree) to use Russian cyrillics. If yes that that for this purpose should be made. At me use of Russian cyrillics in the name item leads to a mistake 1) Error type:LoadXML Descriptin:Incorrect XML
The component is encoding agnostic, and may work with any encoding supported by browser.
To prevent Incorrect XML error you need
a) have correct xml header
<?xml version="1.0" encoding="windows-1251"?>
<item text=“���������” …
b) In case of IE, you need to be sure that xml was sent with correct content-type ( text/xml ) , because in other case - IE will be able to work only with UTF encoding.
