I’d try replacing letters with homoglyphs. Doubt it would work, but not so much that I didn’t think it was worth a try.

I mean, first I’d check to make sure I hadn’t added any leading/trailing spaces. There does appear to be a lot of space before the K. Might technically be why it isn’t working.

Not that the site doesn’t still have serious dumb issues even if that is the issue. But yeah.
