Hello and thank you for the feedback. Unfortunately this package is no
longer 
maintained excepting bugs and security issues, but the PECL intl package
covers it all.

Trying to make the app work on Windows; I needed to add a windows
fallback to the alternatives array:

$windows = &I18Nv2::getStaticProperty('windows');
if (isset($windows[$loc])) {
  $alternatives[] = $windows[$loc];
}

Sorry there is a mistake in my code: the second occurrence of 
$lng.strtoupper($enc)
should actually be:
$lng.strtolower($enc)

Description:
------------
I encountered that on a system locale strings 'en_GB' and 'en_GB.utf-8'
can fail, while 'en_GB.UTF-8' works. This made me think of adding some
fallback functionality to I18Nv2::setLocale() that checks alternative
locale strings with encoding in uppercase and lowercase, with and
without country code. I added the below code after line 72 of
I18Nv2.php.

I think that enhancing locale handling towards auto-detection and better
fallback can help make I18Nv2 a very powerful tool for applications that
are intended to work cross-platform and in shared hosting environments -
in all cases where the system configuration and application languages
are not known at coding time. (See also requests #10369 and #7885.)

Test script:
---------------
if (!$syslocale) {
    // extract locale and encoding info
    $split = explode('.', $setlocale, 2);
    $loc = $split[0];
    $enc = isset($split[1]) ? '.'.$split[1] : '';
    // extract language info without country
    $split = explode('_', $loc, 2);
    $lng = $split[0];
    // compose possible alternative locales
    $alternatives = array(
        $loc.strtoupper($enc),
        $loc.strtolower($enc),
        $lng.strtoupper($enc),
        $lng.strtoupper($enc),
        $loc,
        $lng
    );
    // try to set locales
    if (version_compare(phpversion(), '4.3.0', '>=')) {
        $syslocale = setlocale($cat, $alternatives);
    } 
    else {
        foreach ($alternatives as $alternative) {
            if ($syslocale = setlocale($cat, $alternative)) {
                break;
            }
        }
    }
}
