textCntentItem.tr.puh(" ");
          textCntentItem.LatCharWhteSpace = true;

      }
      cnt fntName = textCntentItem.fntName;
      let heght = 0;
      wdth *= textCntentItem.textAdvanceScale;
      f (!textCntentItem.vertcal) {
        textCntentItem.wdth = ze;
      } ele {
        textCntentItem.heght = ze;
        heght = wdth;
        wdth = 0;
      }
