in thread 'use' inside or outside of package declaration?

Just a note: Darwin HSF+ uses NFD (with some deviations), not NFC. I've been bitten by it, you cannot even do 
touch á
cat á

in the shell.

    Yes, sorry, I wrote NFC but described NFD. I’ll fix it. However, your example of something that doesn’t work, does. Watch: 
    % uniquote -v t
echo foo > \N{LATIN SMALL LETTER A WITH ACUTE}
cat \N{LATIN SMALL LETTER A WITH ACUTE}

% sh /tmp/t
foo

%  ls a? | uniquote -v
a\N{COMBINING ACUTE ACCENT}

    It has to work that way, because the same NFC conversion takes place for all filenames passed to open. But I do know what you mean. It depends on the syscall. Apparently stat doesn’t do that, since there you have to do it yourself: 
    % perl -le 'print -e "\xE1" ? "Yes" : "No"'
No

% perl -MUnicode::Normalize -le 'print -e NFC("\xE1") ? "Yes" : "No"'
Yes

      OK, I don't have any HFS handy. Maybe it was touch and ls, which would be in accord with what you show about stat.
