[reportlab-users] Problem using FAQ example for embedding font

[Gerry Reno]

I changed this line:
justFont = pdfmetrics.Font('GnuMICR', faceName, 'WinAnsiEncoding')

to this which makes more sense:
justFont = pdfmetrics.Font('GnuMICR', faceName, 'FontSpecific')

but now I get this error:

Traceback (most recent call last):
File "./tinyerp-server.py", line 170, in <module>
addons.register_classes()
File 
"/usr/lib/python2.5/site-packages/tinyerp-server/addons/__init__.py", 
line 250, in register_classes

line 64, in <module>
justFont = pdfmetrics.Font('GnuMICR', faceName, 'FontSpecific')
File "/usr/lib/python2.5/site-packages/reportlab/pdfbase/pdfmetrics.py", 
line 360, in __init__
self.encoding= getEncoding(encName)
File "/usr/lib/python2.5/site-packages/reportlab/pdfbase/pdfmetrics.py", 
line 652, in getEncoding
return _encodings[encName]
KeyError: 'FontSpecific'

So what can I do to get pdfmetrics.py to process a non-standard single 
byte font with font specific encoding?
