Menu Links with polish characters not allowed

Hallo there,

I’m running a polish shop on shopify, which has added metafields. These metafields are used for filtering the page as well. But now we have a problem:

Although the filtering is working perfectly fine, the URI contains the filter with polish signs. For example: “ł ż ź ó ń ś ć”. I now have added menu entries with that filters as URL e.g.:

  1. https://reblo.pl/collections/all?filter.p.m.custom.chakras=Gardło

  2. https://reblo.pl/collections/all?filter.p.m.custom.element=Woda

The first link contains a polish character. Which is somehow problematic, as I want to link in the menu the menu entry to:

“/collections/all?filter.p.m.custom.chakras=Gardło”

As I try this, I get the following message:

This shows up, every time I use polish signs.

Please advise, how I can realize the filtering through link with polish characters

Best Regards,
