$title = "Hunting, Tactical & Outdoor Optics eCommerce Store Γ?? $595,000 Γ?? SOLD";
$title = str_replace(html_entity_decode('–', ENT_COMPAT, 'UTF-8'), '-', $title);
$title = str_replace(html_entity_decode('—', ENT_COMPAT, 'UTF-8'), '-', $title);
Replacing the character right away won't work. html_entity_decode
is definitely needed.
