UTF-8 is a variable-width character encoding used for electronic communication.

Should I use utf8mb4?
if you’re using MySQL (or MariaDB or Percona Server), make sure you know your encodings. I would recommend anyone to set the MySQL encoding to utf8mb4. Never use utf8 in MySQL, there is no good reason to do that (unless you like tracing encoding related bugs).
