Under OSes that have UTF-8 as default 1 byte encoding, CP_ACP should behave
as if it were UTF-8.

The whole idea is that you mark the outside world with CP_ACP, and your own
internal encoding UTF-8. (or unicodestring, the principle doesn't depend on
that), and the RTL makes the conversion from ACP to UTF8 automatically.
 
So manually setting CP_UTF8 as system encoding is a workaround, not a long
term solution.
