Error searching for Equipment Packs

[cjo1pal]

I might just need to php code help, but I have a website that uses this API for the data. When searching through the equipment, my results always return invalid when I search for any equipment packs, ie Explorer's pack (equipment/155 - 160).
I also can only however search for items like Alchemist's supplies (equipment/161-177) if I copy and paste it directly from the overall list.
The apostrophe doesn't match what the keyboard inputs.
{"name":"Scholar's Pack","url":"http://www.dnd5eapi.co/api/equipment/160"},{"name":"Alchemist’s supplies","url":"http://www.dnd5eapi.co/api/equipment/161"}
