Description Daniel Tröder

It is possible with UDM to create container/ou objects (and possibly others) that contain non-printable characters like the BOM (U+FEFF).

When that happens, it is most certainly unintended and undesired by the customer.

The error may not be detected at first glance, because the characters are not printed, but later they may lead to stability or security problems in secondary systems.

Limit the allowed characters for container names to those, that customers can type and see.
