How to support full Unicode in MySQL databases

Read Original

This technical article details the limitations of MySQL's 'utf8' charset, which only supports 1-3 byte UTF-8 characters and fails on 4-byte characters like emojis. It explains the difference between 'utf8' and the full 'utf8mb4' encoding, demonstrates the issue with code examples, and provides guidance on how to migrate databases to support all Unicode symbols.
