        ) {
          records.push(r);
        }
      }
      for (i = 0, ii = records.length; i < ii; i++) {
        const record = records[i];
        if (record.length <= 0) {
          continue; 
        }
        const pos = start + stringsStart + record.offset;
        if (pos + record.length > end) {
          continue; 
        }
        font.pos = pos;
        const nameIndex = record.name;
        if (record.encoding) {
          
          let str = "";
          for (let j = 0, jj = record.length; j < jj; j += 2) {
            str += String.fromCharCode(font.getUint16());
          }
