Running the tests with make LANG=C.UTF-8 works.

[Marc André Tanner]

The C.UTF-8 locale isn't in upstream glibc (see also #20), so it would break on different systems.

I suggest to set the environment variable to something suitable for your system.

[Paride Legovini]

If the test result is locale-dependent then the right locale should be set by the test script I think. What about setting LANG=en_US.UTF-8?
