Delphi 2009 - String values - the tkUString and varUString types are not processed in some situations

FROM B130594 ("Delphi 2009 - String fields are not correctly handled with the TcxPropertiesStore")
============================

Additionally I would like to attract you attention to other cases in DevExpress code where tkUString and varUString are not processed. It is worthwhile to perform search for tkString, varString and similar patterns in all code and consider proper handling of new Unicode types. It seems to me that there are several other places that should be considered carefully.

Suspicious places (sorry if I am repeating already known and fixed problems, I simply want to make sure that nothing is missed):

  1) Unit cxBarEditItem.pas

procedure WriteVariantProperty(AWriter: TWriter; AInstance: TObject;
  const APropName: string);

  2) Unit cxFilter.pas

function TcxFilterOperator.GetExpressionValue(const AValue: Variant): string;

  3) cxVariants.pas

procedure WriteVariantProc(AStream: TStream; const AValue: Variant);

and probably some other places

  4) cxStorage.pas - should be considered carefully!

  5) cxXLSExport.pas - may have obviuos problems with varUString

  6) cxImageComboBoxItemsEditor.pas

function TfmImageComboBoxItemsEditor.GetVarTypeName(AVarType: Word): string;
function TfmImageComboBoxItemsEditor.ValueToValueType(var AValue: Variant; AValueType: Word): Boolean;
