MySQL 5.5 - How to change MySQL default character-set to UTF8

2. Run the below script to check the current installed character set.                                                    

     
   show variables like “collation_database”;
    
   +--------------------+-------------------+
   | Variable_name      | Value             |
   +--------------------+-------------------+
   | collation_database | latin1_swedish_ci |
   +--------------------+-------------------+
   
   show variables like "%character%"; show variables like "%collation%";
   
   +--------------------------+----------------------------+
   | Variable_name            | Value                      |
   +--------------------------+----------------------------+
   | character_set_client     | utf8                       |
   | character_set_connection | utf8                       |
   | character_set_database   | latin1                     |
   | character_set_filesystem | binary                     |
   | character_set_results    | utf8                       |
