multi select URL parameter pipe symbol is no longer supported in browsers

Browsers changed behaviour and the pipe symbol | when it appears in a link URL is now filtered (removed) when clicked. I had a link that used the pipe symbol to successfully combine two product categories for instance with /tienda/?wpf_filter_cat_1s=cat1|cat2 until suddenly it no longer worked. It appears when you hover the link and it still works when handwritten, but when clicked as hyperlink the symbol is simply removed to become /tienda/?wpf_filter_cat_1s=cat1cat2

It apparently is now considered an unsafe character according to RFC1738: https://forum.xojo.com/t/how-to-showurl-in-browser-if-url-contains-a-pipe-character/43721/2

Could you please change your filter code that it will accept another symbol like a comma or that it accepts %7C as alternative? Thank you!
