I found the answer! It’s inspired by this answer
$title = "Hunting, Tactical & Outdoor Optics eCommerce Store ΓÇô $595,000 ΓÇö 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.
