We can't agree that "gut" is a word on a page "regardless of the language and its meanings." It might be a random pattern of spilled ink. Only by regarding the language and its meanings can we agree that "gut" is a word on a page.
When I see Arabic written, I only see random markings on a page, but, because of the type of writing, I believe that they are letters that someone with greater knowledge than I can decipher.

Maybe, maybe not. While you jump to a conclusion that it must not be a word; I'm not ready to make such a leap. Frequently, when I have seen an unknown combination of letters, like FWIW, I will search to see if that combination has meaning. I don't automatically dismiss it as nothing because I don't yet understand it.
