two weeks ago (Feb 5th) I wrote a mail concerning problems with torque and unicode.
We now patched the SQLExpression class to work with unicode correctly. Are you in general aware of the problem with unicode? Are there any plans to solve this issue in the upcoming RC2? We could provide a patch for this class.
Another problem we had some weeks ago was the limit/offset problem with MSSQL. We also found a solution for this using inner select statements. We could also provide a fix for this issue.
Best regards.
