I am afraid that the risk that would be involved in configuring 
sun.jnu.encoding exceeds the benefit it would bring, as the encoding is 
so baked in the basis of the Windows Java runtime. Since Microsoft 
itself now recommends users choose UTF-8 as the ANSI code page (over 
changing apps to use -W APIs)[1], I think we would want to wait for that 
glorious day.
