UTF-8 Encoding Explained (MySQL Server Doesn't Think It's Real?!)

In this SQL interview questions and answers video we'll provide some insight into the UTF-8 implementation in MySQL Server, MariaDB Server, and Percona Server. The UTF-8 character encoding standard is some of the most popular character encoding standards SQL databases have to offer. If you watch this SQL basics tutorial in its entirety, you will learn that in MySQL Server, it's not entirely real. You see, the problem with UTF-8 in MySQL Server is that it supports up to 3 bytes per character. With some characters, such an implementation can cause problems. Some SQL characters may display incorrectly, as "?" signs, or the like. Newer versions of MySQL Server overcome this issue, but if you are searching for a quick and easy solution, switch your database character set to utf8mb4. Also make sure to not provide user input straight into SQL queries to avoid sql injection, brush up on sql joins if you feel the need to, and make sure to subscribe to this sql tutorial channel to learn what the core differences between sql vs nosql are.
