[Observium] Bug concerning text with special characters

Hello Observium team, Just found a little bug concerning text with special characters, as attached with this message. It's strange because the text is correctly displayed just below. And the result is all my devices are not in the same group, I cannot do something because the regional settings are automatically filled and managed by Observium, from the name of the town (as I set in the snmp parameters of my devices). Can you check this point ? Thanks, best Aurélien
