No hits when using ‘ character in search requests

Goodmorning,

First of all, thank you for creating this plugin, it works very nice. I’m using the search input in my header for example and and I’m having a question about using special characters in my search request. It seems like I don’t get results if I use the ‘ character in my request. I see the options in the suggestions dropdown though, but when I hit enter then it can’t find any products. So:

No hits after hit enter when searching for:
– Assassin’s Creed

These special characters works though:
– (zie tekst)
– , Xbox
– koopje!

Thank you in advance,

Kind regards,
Wendy
