How can… Re: Packing unsigned long into Unicode characters 14 Years Ago by Ancient Dragon UNICODE characters is wchar_t, which on MS-Windows is unsigned short and on some other operating systems can be unsigned long. So why not just do something like this?

I've tried a similar method, and it didn't work (either resulted in errors when opening the file in a unicode text editor, or simply didn't print the characters).
