Due to a difference between *nix and win32 unicode character sizes
(4 vs. 2 bytes), personally I prefer to avoid such an ambiguity and
simply use plain 0 instead. But '\0' will work just fine.

IMO Wine should not use L prefix at all and explicitly convert ANSI
to unicode when it's needed or use explicit unicode character constants:
static const WCHAR fooW[] = {'f','o','o',0};
but never L"foo".
