I don't think it's random, but I don't know that we have any kind of  
process to update it other than when we get a request to do so and  
find out that the charset (or name) is supported.

That sounds reasonable. do you know how much changes that procedure  
would cause?

Encode::HanExtra will not be necessary, in 5.8 Encode::TW and  
Encode::CN seem to cover them, according to Encode::HanExtra's doc.  
But we would have to keep on eye on others, for instance  
Encode::Arabic, Encode::JIS2K, Encode::IBM
