Now I think you are right. EnumValidator should convert unicode
values to strings because that how SQLObject currently works -- it uses
str internally and is at most unicode-aware.
So my plan is to move method getDbEncoding from SOUnicodeCol to SOCol
and use it everywhere validators need the encoding. The change is rather
big so I will only apply it (if the approach will work at all) to
branches 1.5 and the trunk.
