Do BS2000 conversion implementations that convert between these charsets and Unicode/ISO 10646 only 
use roundtrip mappings, or do they also use fallback/one-way mappings? I assume that all mappings in 
the supplied tables are roundtrip mappings.

What substitution character byte sequence is used for these charsets? It should be added to the 
registration. Is it the same for all of them? (IBM's SUB character for EBCDIC SBCS is 0x3F.)

See "fallback" and "substitution" in http://www.unicode.org/reports/tr22/
