It's a bad thing to do for attention, like hacker elite speak using numbers would be, but is that why the author did that? Did you read the article? It's about a file that can be read by all Unix, Windows, and MacOS. Part of how that happens is one OS mistakes some other text for executable code while the other OS doesn't.

Therefore the title of the article written in multiple language letters and somewhat readable in one language despite that is a good introduction.
