On second thought, remove regex.linux.utf8 regression test altogether. The code-coverage report says that this test doesn't increase coverage by one single line, which I now realize is because I made src/test/modules/test_regex/sql/test_regex_utf8.sql to cover all the code that this would. So really it's pointless and we should just drop it.
