        MySQL 5.7 Release Notes
        
The following applies to replication between MySQL servers that use different character sets:
- If the source has databases with a character set different from the global - character_set_servervalue, you should design your- CREATE TABLEstatements so that they do not implicitly rely on the database default character set. A good workaround is to state the character set and collation explicitly in- CREATE TABLEstatements.
