0 is sort of a switch to make using "the current system Windows ANSI
code page", which is the one you'll get via GetACP, I think.
Another notice: I also set the second parameter simply to 0, but you
may have to use 1 instead to make 100% sure, which has never been
necessary in my case.

Actually this is needed to get the size of the will-be-returned
unicode string, so "xString" doesn't play a role here. You can simply
use the following instead:
iwNum=dll.call("MultiByteToWideChar|ui ui s i ui i",;;+
0,0,"sString",-1,0,0)

I think you mean the surrogate pair in UTF-16, right? I suppose it
would be counted as 2 wide characters, not simply as 1 wide character,
so *2 would be enough. However, I'm not 100% sure about this.
Actually there is a 6-byte overhead in ByteBlock which I simply
ignored here. If it would still crash PP, you may have to use
iwNum*2+6 instead (:iwNum*2+5 may be enough, to be precise).
BTW, I think Alan already implemented a mechanism to appropriately
resize/allocate the needed memory blocks, but it doesn't work somehow
as expected (:I also tried, x1000 for example, however didn't work
either).
