 Please open an issue with Homebrew. This line shouldn't be there:

 The GHC build system sets `-Wno-unicode` by default when HS_CPP_CMD is
 `clang`:
 {{{
  $HS_CPP_CMD -x c /dev/null -dM -E > conftest.txt 2>&1
    if grep "__clang__" conftest.txt >/dev/null 2>&1; then
      HS_CPP_ARGS="-E -undef -traditional -Wno-invalid-pp-token -Wno-
 unicode -Wno-trigraphs"
 }}]
