Using/Displaying special characters in RadComboBox

HOW-TO
Use/display special characters in RadComboBox

SOLUTION
Below are the two possible scenarios:

Defining the combobox structure through XML
If you use a xml file to populate the combobox, you need to set the proper character encoding at the top of the page. For most European languages, you have to use encoding="ISO-8859-1" at the top of the xml file, i.e.

<?xml version="1.0" encoding="ISO-8859-1"?>
<Items>
 <Item Text="Sofia" Value="1" />
 ....................


Defining the combobox structure programmatically
In general, RadComboBox should display special characters as long as you set the appropriate charset encoding in your HTML/ASPX page. Here is an example:

<meta http-equiv="Content-Type" content="text/html; charset=windows-XXXX">

You will need to find the proper charset for the needed language and you should be done.
