utf8 VS utf8mb4

[j.silver]

Dear all,

 

I came across the following statement on one website:

"Note: Since MySQL 5.5.3 you should use utf8mb4 rather than utf8. They both refer to the UTF-8 encoding, but the older utf8 had a MySQL-specific limitation preventing use of characters numbered above 0xFFFD."

 

1) Is there any drawbacks in using utf8mb4, or it is recommended for use from now on?

According to that note they're recommending that you use it.
