For an X instead of a √:

FILLED_CHECKBOX = "\xE2\x98\x92" # "☒"

To get the font to load, I needed:

font("#{Prawn::BASEDIR}/data/fonts/DejaVuSans.ttf")

Nice work!

And for when you go to Ruby 192 the Unicode codes are:
"\u2610" # "☐"
"\u2611" # "☑"
"\u2612" # "☒"

With newer versions of Prawn, you'll get RuntimeError: Bad font family from the above. Easy fix though: use the block version of font:

font "fonts/dejavu/ttf/DejaVuSans.ttf" do
  text "#{CHECKBOX} Not done yet"
end

Also, you can use formatted_text so the label is in your default font:

EMPTY_CHECKBOX   = "\u2610" # "☐"
CHECKED_CHECKBOX = "\u2611" # "☑"  I don't use this, but you could.
EXED_CHECKBOX    = "\u2612" # "☒"
CHECKBOX_FONT    = "#{Prawn::BASEDIR}/data/fonts/DejaVuSans.ttf"

def checkbox(label, checked)
  box = checked ? EXED_CHECKBOX : EMPTY_CHECKBOX

  formatted_text [
    { text: box, font: CHECKBOX_FONT },
    { text: " #{label}" }
  ]
end
