    Specification Shell and Utilities Issue 6
    Location in Spec From the specification of the find utility in Open Group Base Specifications Issue 6.
    Problem Summary The find utility may fail to properly collate or classify files whose names contain characters from
    the non-portable character set.
    Problem Text These tests work 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, or
    otherwise obey the localization rules associated with the test locale. 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 find command expects.

    Note that the assertions being tested are:
    # When the environment variable LC_ALL is set to a non-empty string
    # value, then this value shall override the values of all the other
    # internationalization variables.

    # When the environment variable LC_CTYPE is set to a non-empty string
    # value, then it shall be used to determine the locale for the interpretation
    # of sequences of bytes of text data as characters and the behavior of
    # character classes.

    # When the environment variable LC_COLLATE is set to a non-empty string
    # value, then it shall be used to determine the locale for the behavior of
    # ranges, equivalence classes and multicharacter collating elements within
    # bracket expressions.

    # When the environment variables LC_ALL, LC_CTYPE, LC_COLLATE, and LC_MESSAGES
    # are unset or null and LANG is set to a valid locale, then grep uses the
    # value of LANG to determine default values for each of the locale
    # categories.

    and our Implementation of find does satisfy these requirements. But the combination of the test
    method used and the peculiarity of the file system encoding obscures this.

    I should note that these test cases are 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."
