By default the Charset property is empty. That means there is no action performed with charset on the client and on the server. You can set the Charset property value to 'auto'. In this case, the server asks for the charset and sets the appropriate charset on the client.
Note: You also can use the Unicode property to transfer all data to the UTF8 charset, but it may significantly reduce network traffic and thus decrease the application performance. If the Use Unicode property is set, the Charset property will be ignored.
