now am searching for "**made is**" but its not showing in the pdfjs

and while selecting and copying pdf  text it has no space in b/w words

const ranges = getRanges(glyphs, numGlyphs);
  const numTables = ranges[ranges.length - 1][1] > 0xffff ? 2 : 1;
  let cmap =
    "\x00\x00" + 
    string16(numTables) + 
    "\x00\x03" + 
    "\x00\x01" + 
    string32(4 + numTables * 8); 
  let i, ii, j, jj;
  for (i = ranges.length - 1; i >= 0; --i) {
    if (ranges[i][0] <= 0xffff) {
      break;
    }
  }
  const bmpLength = i + 1;
  if (ranges[i][0] < 0xffff && ranges[i][1] === 0xffff) {
    ranges[i][1] = 0xfffe;
  }
  const trailingRangesCount = ranges[i][1] < 0xffff ? 1 : 0;
  const segCount = bmpLength + trailingRangesCount;
  const searchParams = OpenTypeFileBuilder.getSearchParams(segCount, 2);
