On Alpine Linux 3.7.0, which uses musl libc, this test fails:

The issue is that in the C locale, musl uses the encoding that maps
0x00..0x7F -> U+0000..U+007F
0x80..0xFF -> U+DF80..U+DFFF
Whereas for older platforms it was natural to use the ISO-8859-1 encoding:
0x00..0x7F -> U+0000..U+007F
0x80..0xFF -> U+0080..U+00FF
This patch fixes the test.
Now this test fails on GNU/Linux - at least here on openSUSE-Tumbleweed.
