SYMPTOMS
When you try to fetch data that contains special characters such as carriage returns or line feed by using Microsoft ADO and the Microsoft Data Access OLE DB Persistence Provider (MSPersist), users may receive the following error message:
CAUSE
This behavior occurs because Microsoft Data Access OLE DB Persistence Provider (MSPersist) invokes Microsoft XML Parser (MSXML) 3.0 in Microsoft Data Access Components (MDAC) 2.7. MSPersist invokes MSXML 2.6 in MDAC 2.6. MSXML 3.0 enforces the XML spec wherein it does not permit characters below 0x20H, with some exceptions.
