Also using the **Windows API** :

    when defined(windows):

        pInputControl: pointer

      proc consoleReadLine*(line: var string): bool =

          if numberOfCharsRead == bufferSize and buffer[bufferSize - 1].int ==

            discard readConsoleW(stdin.getOsFileHandle, newWideCString("", 1),

          elif numberOfCharsRead > 1 and buffer[numberOfCharsRead - 2].int ==
