Entities are not renamed along the Device when containing unicode characters

[CFenner]

The problem

I have a device that contains ß, the entity ids have been created with a ss instead, which is correct. However when renaming the device, when the user friendly name is transformed the ß is just replaced with s and the prefix does not match.
