How/why can toStringz() and toUTFz() be used as properties?

You might want to look at std.windows.charset. You'll find the following 
functions:

	const(char)* toMBSz(in char[] s, uint codePage = 0)
	string fromMBSz(immutable(char)* s, int codePage = 0)

These might work for you or you may be able to expand on them.
