I have some text in a non-English/foreign language in my page, but when I try to make it lowercase, it characters are converted into black diamonds containing question marks.
$a = "Երկիր Ավելացնել";
echo $b = strtolower($a);
//returns ����� ���������
I've set my charset in a metatag, but this didn't fix it.
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
What can I do to convert my string to lowercase without corrupting it?
Have you tried using mb_strtolower()?
