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 @).
