[reportlab-users] How to create special micr control character in Reportlab

Does the CMC-7 TTF include these characters, as well? I can reproduce all these special CMC-7 characters nicely with a font named Code2000 (easy to find on the net), which is supposed to include all Unicode codepoints. See the code below and the attached PDF it generates.

from reportlab.lib.units import cm
from reportlab.pdfgen.canvas import Canvas
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont

font = TTFont("Code2000", "/Fonts/truetype/Code2000.ttf")
pdfmetrics.registerFont(font)

canv = Canvas("cmc-7.pdf")
canv.setFont("Code2000", 24)
canv.drawString(9*cm, 22*cm, "Hello World!")
cmc_chars = ' '.join([unichr(i) for i in range(0x2440, 0x244a)])
canv.drawString(9*cm, 21*cm, cmc_chars)
canv.showPage()
canv.save()
