Wide characters

[hacker1024]

I need to decode wide character (wchar_t) strings. The size of wchar_t can vary between platforms; on Windows, for example, it's 2 bytes (UTF-16) , but on macOS, it's 4 (UTF-32).

At the moment, there's no easy way to decode these characters properly. It's be great if something like a WChar type was created, and there was a function on Pointer<WChar> to generate a string.

This is tracked in dart-lang/sdk#42563.

dart-lang/sdk#42563 covers the wchar_t type representation in Dart, but once this is resolved, a utility function to handle string conversions should still be implemented in package:ffi. Can this issue stay open?
