I'm quite unsatisfied with the current handling of character sets in the 
build in general. :-( I'd really like to modernize it. I have a, 
slightly fuzzy, laundry list of things I want to fix from a build 
perspective, but I'm not sure of what "external" requirements are coming 
from AIX and the general core-libs agenda regarding character sets in 
general.

I think there is a good opportunity to solve many problems at the same 
time here, as long as everyone agrees on what is the preferred outcome.

As always, please include build-dev in build related discussions.
