More strictly, UNIX doesn’t have “type” in a file. They’re just a bunch of bytes. It’s
up to whoever is making the file to decide if the name conveys that information or a magic
number does.
The other fun character set was the old UNIVAC Fielddata. There were no non printing
characters and in fact not even a null value (the 0 value was called master space and
printed as @).
