Hello, The test "terminal-string-width Japanese" in the file "tests/syscalls.scm" has an environmental dependency which causes it to fail when I run `guix shell --pure -D guix -- make check TESTS=tests/syscalls.scm`. I can resolve this by instead running `guix shell --pure -D guix -- env LANG=en_US.utf-8 make check TESTS=tests/syscalls.scm`. I do not know enough about locales to know if it makes sense for the test to set the environment variable, to make a recommendation in the manual, or to do something else. For bootstrapping, which requires some programs not included in the package dependencies, the manual specifically states the additional packages which are required (the problem here is not an additional package, but seems similar).
Regards, Skyler
