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

this.cidEncoding.startsWith("Identity-")
    ) {
      const cidToGidMap = properties.cidToGidMap;
      
      
      const map = [];
      applyStandardFontGlyphMap(map, getGlyphMapForStandardFonts());
      if (/Arial-?Black/i.test(name)) {
        applyStandardFontGlyphMap(map, getSupplementalGlyphMapForArialBlack());
      } else if (/Calibri/i.test(name)) {
        applyStandardFontGlyphMap(map, getSupplementalGlyphMapForCalibri());
      }
      
      
      if (cidToGidMap) {
        for (const charCode in map) {
          const cid = map[charCode];
          if (cidToGidMap[cid] !== undefined) {
            map[+charCode] = cidToGidMap[cid];
          }
        }
        
        
        if (
          cidToGidMap.length !== this.toUnicode.length &&
          properties.hasIncludedToUnicodeMap &&
          this.toUnicode instanceof IdentityToUnicodeMap
        ) {
          this.toUnicode.forEach(function (charCode, unicodeCharCode) {
            const cid = map[charCode];
