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
