Managed StringElement garbles the .net string assigned to it

Description
Create a ODBC provider connection to MSTest.mdb in the GenericRdbms unit test directory
Execute an IDescribeSchema with:
SchemaName = "Fdo" ClassNames = { <any table in that database> }
The execution will fail, and the provider will report the following message:
Unable to find class '<table name>'
The only thing here is that <table name> has been somehow garbled by the provider, and I am assuming it is trying to execute under this garbled name.
For example: 'Cities' gets turned into 'ቈܮties' by the provider.

| Summary: | ODBC provider garbles the specified class name when using enhanced IDescribeSchema → Managed StringElement garbles the .net string assigned to it |
In writing the attached sample code, I've discovered that the StringElement wrapper class is quite possibly the culprit here.
When you feed a .net string to a new StringElement instance, inspecting the String property (StringElement.String) returns a garbled version of the original string.
