What can be a problem

Does it always fail on the same parameter?

I'd probably do it like this, but it depends on the declaration and description of the GetOptParameter method.

  var
    FNameOut: AnsiString;
  begin
    ...
    FNameOut := UTF8Encode(ParamName);
    if FDSBase.GetOptParameter(0, FieldNo, @FNameOut, ParamType,  ...
