add uft8 validation for safe volume label exporting

# udev-test
#
# Provides automated testing of the udev binary.
# The whole test is self contained in this file, except the matching sysfs tree.
# Simply extend the @tests array, to add a new test variant.
#
# Every test is driven by its own temporary config file.
# This program prepares the environment, creates the config and calls udev.
#
# udev parses the rules, looks at the provided sysfs and
# first creates and then removes the device node.
# After creation and removal the result is checked against the
# expected value and the result is printed.
