according to this post https://mathiasbynens.be/notes/mysql-utf8mb4 the default utf8 in mysql do not exactly match utf8 standard (3 vs 4 bytes) Since it maps to the same charset in Java It sounds like the reasonable thing to do is to change the used protocol from 83 to 224 (utf8mb4_unicode_ci) I added a flag to allow overriding it `-DjasyncMysqlUTF8Collation=83` To put in back in the old legacy behaviour for example if using mysql server < 5.5.3. Added also tests for this.

@oshai Thank you! It looks good to me. Maybe we could add that flag to the document in case someone is using a version of MySQL released 9 years ago. |

It sounds like the reasonable thing to do is to change the used protocol
from 83 to 224 (utf8mb4_unicode_ci)
I added a flag to allow overriding it
-DjasyncMysqlUTF8Collation=83To put in back in the old legacy behaviour
for example if using mysql server < 5.5.3.
Added also tests for this.
