If you are going to manipulate spaces into other things in Unicode there are already so many fun tools like non-breaking spaces and half-width spaces and medium mathematical space. You could even go for weird, rare ASCII-compatible like "form feed". https://en.wikipedia.org/wiki/Whitespace_character https://en.wikipedia.org/wiki/Whitespace_character Seems more fun to use something that exists, is rare, and is already weirdly space-like. (Though yes, you have to find a way to escape it if someone is crazy enough to do something like name a file with a "form feed" in the middle.)
