Unknown character set: 'utf8mb4'

utf8mb4 wasn't available until MySQL/5.5.3 but HeidiSQL generates this on SQL dumps:

/*!40101 SET NAMES utf8mb4 */;

... which leads to:

/* SQL Error (1115): Unknown character set: 'utf8mb4' */

... on older servers. I guess it should be:

/*!50503 SET NAMES utf8mb4 */;

... or maybe:

/*!40101 SET NAMES utf8 */;
/*!50503 SET NAMES utf8mb4 */;

... for some kind of backwards compatibility.

In my case, source database was using utf8_spanish_ci so I don't need really full UTF-8.

P.S. Love markdown support in forum!

In SQL dumps, make "SET NAMES utf8mb4" a version conditional statement for the minimum MySQL version supporting that charset. See

Yes, think you're right.

Done in r5034.
