commit bf5a308349fbcf0a376ca3e6e83fe7c6a2cc9eb1
Author: Paul Eggert <address@hidden>
Date:   Wed Dec 25 14:40:11 2019 -0800

    tests: work around AIX 7.2 sh printf bug
    
    AIX 7.2 /bin/sh’s printf command mishandles octal escapes
    in multibyte locales: it treats them as characters, not bytes.
    * tests/backslash-s-vs-invalid-multitype, tests/encoding-error:
    Use the C locale when employing the printf command with an octal
    escape that AIX 7.2 sh might mishandle.
    * tests/init.sh (setup_): Use the C locale for tests.
    This has the side benefit of making them more reproducible.
