INSERT query does not work

I am using 5.6.26…apart from that there is something very weird.

Check these 2 statements…

INSERT ΙΝΤΟ rememb_token ( username)  VALUES( 'test@ath.forthnet.gr');

INSERT INTO rememb_token ( username) VALUES ( 'test@ath.forthnet.gr');

Do you see any difference among the two?

Well the weird is that the firtst outputs a syntax error while the second it runs OK…
I really cannot understand what is going on here…

I really cannot explain it.
