Hello,

The attached patch rectifies a spurious test failure reported at https://bugs.gentoo.org/753677. It increases tremendously the likelihood that test t0251 can be properly conducted by using any available UTF-8 locale for the purpose of defining the system character type, while skipping the test in the event that no such locale can be found rather than assume - potentially incorrectly - that either of en_US.UTF-8 and C.UTF-8 are available.
