Speaking as one who has just invested several very painful solid days 
trying to pick apart 1.3 million data records transmitted in ASN.1/BER 
(the one or two publicly available pieces of software that claimed to do 
BER silently failed to do anything, the information provider's own C 
program was idiosyncratic, failed to compile out of the box, and ran 
painfully slow), and then discovered that all the non-ASCII characters 
are hosed, I hope that this effort bears fruit.

At the moment I am about ready to categorically refuse ever to deal with 
anything that has anything to do with ASN.1. Bah.  -Tim
