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

if (
        properties.hasEncoding &&
        !this.isSymbolicFont &&
        ((cmapPlatformId === 3 && cmapEncodingId === 1) ||
          (cmapPlatformId === 1 && cmapEncodingId === 0))
      ) {
        const glyphsUnicodeMap = getGlyphsUnicode();
        for (let charCode = 0; charCode < 256; charCode++) {
          let glyphName;
          if (this.differences[charCode] !== undefined) {
            glyphName = this.differences[charCode];
          } else if (baseEncoding.length && baseEncoding[charCode] !== "") {
            glyphName = baseEncoding[charCode];
          } else {
            glyphName = StandardEncoding[charCode];
          }
          if (!glyphName) {
            continue;
          }
          
          const standardGlyphName = recoverGlyphName(
            glyphName,
            glyphsUnicodeMap
          );
          let unicodeOrCharCode;
          if (cmapPlatformId === 3 && cmapEncodingId === 1) {
            unicodeOrCharCode = glyphsUnicodeMap[standardGlyphName];
          } else if (cmapPlatformId === 1 && cmapEncodingId === 0) {
            
            unicodeOrCharCode = MacRomanEncoding.indexOf(standardGlyphName);
