Are there Han characters defined in ISO-2022-JP and EUC-JP but not in
Unicode CJK unified ideographs region (and Extended)? In Korean KSX-1001 
standard (formerly known as KSC-5601) there are only 4888 Han ideographs 
defined and there's no problem since CJK ideographs include all of them. 

Making the driver support ISO-2022 shouldn't be hard, but I'm worried 
about reproduction of "Tower of Babel" in 21st century. For example 
ISO-2022-JP and ISO-2022-KR are not compatible and can't used together 
even though they use the same encoding method for representing characters. 
EUC-JP and EUC-KR have the same problem, too. I'd like to see Japanese
and Korean (and many other languages as well) together on a screen.

I'll check it soon. Thank you.
