The issue is that the font has a version 0 OS/2 table 
(http://www.microsoft.com/typography/otspec/os2ver0.htm#ur) which doesn't have 
the unicode / codepage range fields 
(http://www.microsoft.com/typography/otspec/os2.htm). The EOT converter does 
not check the OS/2 version, so it tries to request these fields which don't 
exist, hence the exception being thrown.
