9642 :: What's the name for wchar?

  What's the Nim equivalent for wchar_t in C?

  On my system, sizeof(wchar_t) is 4 (same as Rune), but WideCString in Nim is for UTF-16.

  Should I use something like

  type WChar {.importc: "wchar_t", header: "<wchar.h>".} = object
  Run

  What should its name be? WChar, wchar_t, or cwchar_t?

  I would use

  type Char32 {.importc: "wchar_t", header: "<wchar.h>".} = object
  
  Run

  But some other system may define it as 16-bit, so I don't think this is appropriate.

  True so name it WideCChar but I don't know by which logic it is mapped to 16 or 32 bits as Unicode is not platform specific.

  There must be some historical reasons, I think. I'm trying to wrap some C functions.
