standard-display-table is not guaranteed to be set, so you need to
make sure it is first.  Like this:

  (or standard-display-table
      (setq standard-display-table (make-display-table)))
  (aset standard-display-table 8239 [729])

Note that you can also specify a face for the glyphs in the display
table, which could come in handy if you want them to stand out on
display.
