I'll go ahead and enter in a bug report under the Cocoa Widgetset.

Another piece of information added to the bug report:
Note that the problem seems to occur when I do not include a field length in the for the WideChar fields when creating the table. For example...
I have the issue when working with the table created by the following:
create table test1 (field1 WideChar, field2 WideChar, field3 WideChar)
However, I don't have the issue when working with the table created by the following:
create table test1 (field1 WideChar(8000), field2 WideChar(8000), field3 WideChar(8000))
