CO2 Ampel name corrupt

[sbernhard]

I'm using the latest version of the firmware. First of all, everything works and is really great.

I resetted the device multiple times but the ampel name is always set as in the screenshot.

Of course, the MQTT name is set like this:

PUBLISH from &mqttpass= (d0, q0, r0, m0, 'sensors/&mqttpass='

I don't know why this occurs. Maybe its because of my wifi password which contains the following special chars: -+!@

I would fix it for my own, if I would now in which file... :-)
