 * Encoding data

   ```php
   \Delight\Base64\Base64::encodeUrlSafe('πάντα χωρεῖ καὶ οὐδὲν μένει …');

   \Delight\Base64\Base64::decodeUrlSafe('z4DOrM69z4TOsSDPh8-Jz4HOteG_liDOus6x4b22IM6_4b2QzrThvbLOvSDOvM6tzr3Otc65IOKApg~~');
   // string(58) "πάντα χωρεῖ καὶ οὐδὲν μένει …"
   ```

 * Encoding data

   ```php
   \Delight\Base64\Base64::encodeUrlSafeWithoutPadding('πάντα χωρεῖ καὶ οὐδὲν μένει …');

   ```

 * Decoding data

   ```php
   \Delight\Base64\Base64::decodeUrlSafeWithoutPadding('z4DOrM69z4TOsSDPh8-Jz4HOteG_liDOus6x4b22IM6_4b2QzrThvbLOvSDOvM6tzr3Otc65IOKApg');
