Subject: tests: sort: check byte-wise ordering in the C.UTF-8 locale
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=af1ba4244c292c6cf2dfba3c351edd55cc4c46c5;p=thirdparty%2Fcoreutils.git

tests: sort: check byte-wise ordering in the C.UTF-8 locale

* tests/sort/sort-locale.sh: C.UTF-8 has a UTF-8 codeset but the
collation rules of C, so add a case ensuring the ordering there stays
byte-wise rather than following the linguistic rules exercised for
en_US.iso8859-1 and fr_FR.UTF-8 above.
