To whom it may concern, I encountered the same issue today (on 2.2.16-1).
Thanks to PTDEBUG=1 trace, I found the issue came from the default mysql client charset is latin1.
After added 'default-character-set=utf8' into my.cnf [client] section, the problem solved! : )
Didn't tested, but --charset or A=utf8 should do the magic, too.
