How about:

(aset (or standard-display-table
          (setq standard-display-table (make-display-table)))
      ?- [?\u2013])

Or for just programming language mode foo:

(add-hook 'foo-mode-hook
          (lambda ()
            (aset (or buffer-display-table
                      (setq buffer-display-table (make-display-table)))
                  ?- [?\u2013])))
