The variable utf-translate-cjk must be set via Customize to achieve
the desired effect.  Stefan suggested to make a minor mode such that
people can just invoke that via Lisp and don't have to use Customize.
I was following this discussion and looked at define-minor-mode to do
that.  So I wanted to replace the current (defcustom utf-translate-cjk
...) statement with a (define-minor-mode utf-translate-cjk-mode ...)

The defcustom for utf-translate-cjk contains several keyword args:
:set, :version, :type, :set-after, and :group.  define-minor-mode is
a macro that expands to a defcustom statement.  I couldn't see how to
inject the :version and :set-after keywords into the defcustom
statement generated by define-minor-mode.

Of course, I could also do it manually, as follows:

* Change the :set arg for the current defcustom utf-translate-cjk to
  invoke utf-translate-cjk-mode, instead of the current code.

* Write a new function utf-translate-cjk-mode that does what the
  current lambda expression for :set does.

But what's the point of a convenience macro like define-minor-mode
when I circumvent it?
A preposition is not a good thing to end a sentence with.
