The data handler for the unicode strings may throw in the destructor

[Paolo Brandoli]

If the data handler for unicode strings (writingDataHandlerStringUnicode) cannot encode a string during the commit phase (in the destructor) then it may throw an exception.

It is forbidden to throw exceptions in the destructor.
