    Problem Summary The pax utility may fail to properly collate files whose names contain characters from the non-
    portable character set.
    Problem Text The test works by creating files with single-character filenames from the test locale's character
    set and verifying that the file names collate properly, or are in the proper character class. The file
    system with which we are testing does not encode Latin-1 characters from the non-portable
    character set in the way that the pax command expects.

    Note that the assertion being tested is:
    # When the environment variable LC_ALL is null or not set and LC_COLLATE is
    # set to a non-empty value, then pax uses the value of LC_COLLATE as the
    # locale that should be used to affect the behavior of ranges, equivalence
    # classes and multi-character collating elements used in the pattern
    # matching expressions for the pattern operand and the basic regular
    # expression for the -s option.

    and, in fact, our implementation of pax does satisfy this requirement. But the combination of the
    test method used and the peculiarity of the file system encoding obscures this.

    I should note that this test case is not portable, because of the following requirement from
    Base Definitions section 4.6: "For a filename to be portable across implementations conforming to
    IEEE Std 1003.1-2001, it shall consist only of the portable filename character set as defined in
    Portable Filename Character Set."
