 * Hi, please check and make sure you have mbstring PHP extension enabled.
    Also,
   make sure that charset of your DB is utf8mb4 to be able to store Unicode characters
   in DB tables. Please ask for this your developer or hosting help. Here is more
   info [https://gist.github.com/Xeoncross/5d85c3f5547ee04d5bd81113a2c8ec4d](https://gist.github.com/Xeoncross/5d85c3f5547ee04d5bd81113a2c8ec4d).
   And also, make sure that your WordPress installation is using utf8mb4 as database
   encoding in wp-config.php file. If this will not help, let us know.
