Customizing the check boxes?

[rubyFeedback]

We can select via e. g.

  ⬡ vodka
‣ ⬡ beer

Is there a way to choose another way to indicate what a user could use?

For instance, I would like to use the unicode check box instead ☑. Similarly for
the non-choice the empty unicode box. (Or perhaps ☐ U+2610 or something
like that.)

I don't know how to customize tty-prompt for that, though.
