Here is a solution to sort German UTF-8 page names, so characters äöüÄÖÜß
are placed within the alphabet:
// [(search .... sort=de )]
function BOLTsortDe($list) {
usort($list, 'compareItemsDe');
return $list;
}
function compareItemsDe($a, $b) {
$anew = decodeDiacritics($a);
$bnew = decodeDiacritics($b);
if ($anew < $bnew) return -1;
if ($anew > $bnew) return 1;
return 0;
}
function decodeDiacritics($x) {
$map = array(
'%c3%84' => 'ae',
'%c3%96' => 'oe',
'%c3%9c' => 'ue',
'%c3%a4' => 'ae',
'%c3%b6' => 'oe',
'%c3%bc' => 'ue',
'%c3%9f' => 'ss',
);
return str_replace(array_keys($map), array_values($map), $x);
}
