Filter by text field or title with slash character included

I have facet of select box or link type - field is text plain type (or title), which include string of content "PV/G 21" and similar.
When I filter by it in facet, url is http://sitename.test/[view_path]/[facet key]/PV/G 133

This does not work, no filter is selected. Is it possible to escape slash somehow in url. If I youse search api preprocessor to ignore slash, it does not appear in facet fileter either.

Thank You.
