The most clean (?) is to compare "git diff" NFC and git diff NFD, they should 
give the same result:
for "git diff" something like this would do:
+
+# This will test git diff
+test_expect_success "git diff f.Adiar" '
+       echo "Modified" >f.$Adiarnfd &&
+       git diff f.$Adiarnfd >expect &&
+       git diff f.$Adiarnfc >actual &&
+       git checkout f.$Adiarnfd &&
+       test_cmp expect actual
+'
