Not Showing: Product tags that have a single apostrophe

Hi,

I’ve just started using this (awesome!) plugin

I’ve got lots of Product tags that have a single apostrophe “’” in them

But it looks like Product Filter won’t Show/Filter these!

In trying to resolve this problem I can see that ‘special characters’ are a bit of a problem, generally, in WordPress tags

Is there a way around this in the Product Filter plugin ??

Can you offer any general advice ??

Best Regards,

Mike
