I am trying to display a product archive page and the product category slug has a "&" in the title but it doesn't work. I understand the & is used to do URL queries and works as a sort of separator.

I've tried the following:

product%26category

Which I hoped it would generate:

product&category

But it actually shows the %26 in the final URL, not the "&" sign.

I've tried adding %26 to the category slug, which upon saving shows a & sign, but then the URL shows just a 26.
