Bug using FOR XML AUTO with columns with type char(1)

Hello,
Having some problems with generating xml with "FOR XML AUTO". Rows with
a column with a value char(0) seems to terminate the row!
Try to run the following:
SELECT
*
FROM (
SELECT
1 AS orderItemId,
1 AS orderId,
CHAR(0) AS orderItemStatus --CHAR(0) terminates row!
UNION
SELECT
2 AS orderItemId,
1 AS orderId,
CHAR(49) AS orderItemStatus
) AS orderItem
FOR XML AUTO
Generates:
<orderItem orderItemId="1" orderId="1" orderItemStatus="
Should be(?):
<orderItem orderItemId="1" orderId="1" orderItemStatus=" "/><orderItem
orderItemId="2" orderId="1" orderItemStatus="1"/>
Anyone seen this before?
Regards, Nils
CHAR(0) is not a valid XML character. In FOR XML, we do not detect invalid
characters for performance reasons, so you will pass the XML anyway.
Depending on what the client code uses to read the XML, it may see the
CHAR(0) and decide that it is the end of the string (for instance, if the
client code uses the standard C/C++ string types).
So the recommendation is: Do not generate XML containing invalid characters
such as CHAR(0) since they are not supported by compliant XML parsers and
may result in other unforeseen behaviour.
Best regards
