See lib/common/msedb.pas, especially tmsestringfield, TField.GetClassDesc does not workfor them BTW. The strings are converted from utf8 or current locale encoding to UCS2 after fetching the data from database and to utf8 or current locale encoding before sending data to the database in order the string encoding needs not to be converted while displaying and editing data in MSEgui. I can say that this concept and the whole MSEide+MSEgui system turned out to be very successful in commercial database applications.
