NumberFormatter::formatCurrency return NaN with "fr_FR.UTF-8"

Question

The following issue occurs with apache on Ubuntu 13.04(not sure about other OS's) I tried with fr_LU too but to no avail

Doesn't work -returns NaN

setlocale(LC_MONETARY, 'fr_FR.UTF-8');
$currency_formatter = NumberFormatter::create(setlocale(LC_MONETARY, "0"), NumberFormatter::CURRENCY);
$currency_formatter->formatCurrency(100, 'USD');

What am I missing here?

Result for locale -a on my machine is as follows:

  C
    C.UTF-8
    de_AT.utf8
    de_BE.utf8
    de_CH.utf8
    de_DE.utf8

Followed a comment at https://bugs.php.net/bug.php?id=54538 which goes as follows: "I have observed a workaround. Setting LC_MESSAGES does not affect NumberFormatter and is sufficient for gettext translations at the same time."

I commented It is a workaround and it worked for me. This is how my code looks after the change

putenv('LC_MESSAGES='.$locale);
setlocale(LC_MESSAGES, $locale);
setlocale(LC_TIME, $locale);
//Don't set LC_NUMERIC and LC_MONETARY as these may interfere with number formatter and cause to return NaN(https://bugs.php.net/bug.php?id=54538)
//setlocale(LC_NUMERIC, $locale);
//setlocale(LC_MONETARY, $locale);

$currency_formatter = NumberFormatter::create(setlocale(LC_MESSAGES, "0"), NumberFormatter::CURRENCY);
