SYMPTOMS
When you try to pass a string across remoting boundaries in the Microsoft .NET Framework 1.1 Service Pack 1 (SP1), you may receive an exception error message that is similar to the following:

Unhandled Exception: System.Xml.XmlException: '♥', hexadecimal value 0x03, is an invalid character. Line 4, position 63.

This problem occurs when the following conditions are true:
 * You make the call across remoting boundaries by using the HttpChannel class and the SoapFormatter class.
 * The passed string contains XML characters that are not valid.



CAUSE
This problem occurs because the SoapFormatter class does not correctly encode special characters when it serialized the string according to the XML specification.
