There are 32 Ctrl+letter combinations which are characters, and the
above two are among them.  These are exceptional special cases due
to history.  My general recommendation is to not use keyboard-translate
but key-translation-map or function-key-map, which work on arbitrary
key sequences rather only on single-char events.

I got these exact keyboard-translate lines from Xah's blog.  They don't work reliably on Windows.  Sometimes after switching back to Emacs from another program, and my first input to Emacs is C-j, C-j still registers instead of C-x.

How would I use key-translation-map to do the swap?

(define-key key-translation-map [(control x)] [(control j)])
(define-key key-translation-map [(control j)] [(control x)])

C-j seems regixter as C-x.  But C-x acting like a prefix key, waiting for the next input.
