I've been working on the wide character x64 version and will likely have that done soon. I'd say I had a pretty lot of troubles. None with my VC 9 from Visual Studio 2008, but VC15 from Visual Studio 2015 is a REAL bear! That's what's been holding me up. I've just lost about 4 days on one issue that appears to be a VC 15 bug. It involves sized deallocations with operator delete.
