You need to prefix "C-x C-f" with "C-x RET c us-ascii RET".  See the
node "Text Coding" in the Emacs manual.

Or use "M-x find-file-literally" to disable any conversions.

Emacs by default visits binary files without any conversions.

Because the file is already in an Emacs buffer, so Emacs doesn't
re-read it, it just reuses that buffer's contents.

Text decoding is not a mode, it is a basic feature of any I/O Emacs
does.
