Official OSF/IANA charset mapping?

["Kresten Krab Thorup (Trifork)" <kr...@trifork.com>]

Does someone know if there is an authoritative specification for the  
mapping between OSF and IANA charsets?  Right now I have something  
that derives from my own experiments, reasonable guesses, and what I  
could find in secondary sources on the net.

Trouble is IIOP uses OSF characterset identifiers, and  
javax.nio.charset encoders are named by the IANA charset names (as  
also used in MIME); and I am using java's own encoders to do the  
transformations.  It seems that nowadays it is only CORBA that is  
still using the OSF charset names for historical reasons.
