Although you are technically correct, I think the days of Latin1 only 
support are simply over and I would prefer to move forward and leave 
them completely behind us. The best way to achieve this is when all VMs 
use UTF-8 everywhere and all VMs produce Unicode input characters. The 
changes to support this aren't difficult (just a bit tedious) and the 
image side is trivial for those images that don't need (or want) to 
support Unicode. I really don't see any value in fiddling with different 
encodings since UTF-8 is both canonical and well supported.
