[freedom] UTF8 vs UTF8MB4

[Saifi Khan]

Merhaba:

Has somebody written a SQL similar to this

CREATE DATABASE testdb DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

What is the difference between UTF8 and UTF8MB4 ?

I need help to understand the memory implication of
- CHARACTER SET utf8mb4
- COLLATE utf8mb4_unicode_ci

Any pointers?


warm regards
Saifi.
