This is what I got when I searched for results with the game Wildermyth key word. Completely unreadable. If I remove the key search word this yellow mess goes away but then so does my search results.

I use Firefox.

Ah, it's probably because of GOG's poor handling of unicode/UTF, among other things. I search for Wildermyth, it only comes up with 3 relevant results, no spaces; I assume that your input method might be putting in 0 width spaces or other weird control characters that GOG doesn't know what to do with/properly truncate, because who would sanitize their inputs?

Thank you Palestine, not sure how that happened. It's working now.
