Re: [IUG] Russian Ligature Display - Combined vs Left/Right Halves

[Bob Rasmussen <ras at anzio dot com>]

I believe you are mixing up character sets. The FE20 and FE21 characters 
belong to the Unicode character set, while the CDA1 belongs to the ANSEL 
character set. 

A MARC file can be coded in either ANSEL or Unicode. But they can not be 
mixed.
