Encoding test incompatible with MS SQL Server

Running it results in this exception:

When I performed the first step of the test described in this link:

http://confluence.atlassian.com/display/DOC/Troubleshooting+Character+Encodings

I get the following error stack:

Cause:
java.sql.SQLException: Argument data type text is invalid for argument 1 of lower function.

Stack Trace: [hide]

This is because the LOWER function in MS SQL can only be performed on fields that can be converted into a varchar (the BODYCONTENT.BODY column that the encoding test is trying to lower is a TEXT or clob-equivalent field in MS SQL).
