No “em dash” on the iPhone? Yes!

Google can’t help: The em dash (—) often demarcates a parenthetical thought — like this one — or some similar interpolation, but i can’t find a way to type one on the iPhone. Can you help?

Apple discussions to the rescue:

If you add the Japaneese QWERTY keyboard to your list of keyboards, you can find it by hitting the 123 button, then press and HOLD the hyphen (-) button, then slide up to select your dash of choice.
