用dephi或c++bulid
怎样从ACCESS中读取MEMO中的数据（unicode编码）再存储到另一个表中同样是Memo属性

我自己写进去是乱码，用TNT控件，数据显示的是？
我的代码如下
data->Close();
        data->SQL->Clear();
        data->SQL->Text = "delete * from result_israel";
        data->ExecSQL();

        data->Close();
        data->SQL->Clear();
        data->SQL->Text = "select * from dictionary_israel where jiexi<>'' order by id";//解释 is not null order by id";
        data->Open();
        ProgressBar1->Max = data->RecordCount;
        ProgressBar1->Min = 0;

        for(int i=0; i<data->RecordCount; i++)
        {
          WideString jieshi,tempstr, kong = "\r\n";
          WideString word = data->FieldByName("Word")->Value;
          WideString datastr = data->FieldByName("jiexi")->Value;

          int pos;
          pos = datastr.Pos("\n");
          if(pos == 0)
          {
          data->Next();
          ProgressBar1->Position += 1;
          continue;
          }
          tempstr = datastr.SubString(1,pos - 2);
          if(tempstr != word)
          {
          data->Next();
          ProgressBar1->Position += 1;
          continue;
          }
          jieshi = datastr.SubString(pos + 1,datastr.Length() - pos);
          write->Close();
          write->SQL->Text = "insert into result_israel (Word,jiexi) values (:a, :b)";
          write->Parameters->Items[0]->Value = word;
          write->Parameters->Items[1]->Value = jieshi;
          write->ExecSQL();

          ProgressBar1->Position += 1;
          data->Next();
        }
        ShowMessage("ok!");
望各位大虾们帮个忙谢谢！！！！！！！！！！
