If dm_task_set_name/newname is called, the name provided will be automatically translated to correct encoded form with the hex enconding so any character not on udev whitelist will be mangled with \xNN format where NN is hex value of the character used. By default, the name mangling mode used is the one set during configure with the '--with-default-name-mangling' option.
