talk will also look at the quirks and oddities you will have to think of when migrating your old MySQL 5.7 data to MySQL in order to take advantage of utf8mb4 and the new collations and cover topics:
- How to migrate to utf8mb4 from latin1, utf8 etc.
- Problems that might arise wrt. uniqueness, indexes etc.
- Pitfalls with character set and collation settings
- How to fix character set data that has for some reason a wrong encoding
