I totally agree. Took me a few minutes before I figured out what it was doing
the first time I saw it :-) This is also done in the existing
`convertUTF8ToUTF16String` wrapper too.
All the implementations of `std::vector` that I know of will work with this,
though as you say it's not guaranteed by the standard.
Looking more closely, I think in this case it was only done for the call to
`stat`, which I've removed. I had added it here too in case the caller relied
on this null trick, but I don't think it's necessary in either place anymore.
I'll remove it.

Hah, yes. I'll replace this with a vector to start with.
