Traccar with MySQL Character error

Hello,
I 'm using Traccar4.6 with MySQL database on Linux Centos7 server and working.
But I got following error when try to change the name of GPS device to Thai language (no error with H2 database) .

Incorrect string value: '\xE0\xB8\x81' for column 'name' at row 1 - SQLException (... < QueryBuilder:480 < DataManager:458 < BaseObjectManager:90 < ...)

How I can fix this problem ?
