Any idea why I get an encoding error with this code?
$date_pre = get_field("date");
$date_s = date("j/n", strtotime($date_pre));
setlocale(LC_TIME,'sv_SE');
$month = strtolower(strftime("%B", strtotime($date_pre)));
$date_l = strftime("%A %e " . $month, strtotime($date_pre));
The $date_pre is a ACF field that contains a date formated like this: 20180518. When I then echo out $date_l, which is a reformated variant of $date_pre that puts in the weekday in swedish with the day number and the name of the month (Lördag 18 maj), it can’t write out “åäö“. "ÅÄÖ" gets replaced with a question mark symbol. It works on my local setup, but not when I upload the theme to a server.
