ObjFW  Check-in [e73c65a849]

    $ objfw-new app MyFirstApp

  This creates a file `MyFirstApp.m`. The `-[applicationDidFinishLaunching]`
  method is called as soon as ObjFW finished all initialization. Use this as
  the entry point to your own code. For example, you could add the following
  line there to create a "Hello World":

    [of_stdout writeLine: @"Hello World!"];

  You can compile your new app using `objfw-compile`:

    $ objfw-compile -o MyFirstApp MyFirstApp.m

  `objfw-compile` is a tool that allows building applications and libraries
  using ObjFW without needing a full-blown build system. If you want to use

 * For example, on Windows XP, when using Windows XP's console, changing the
 * codepage to UTF-8 mostly breaks write() and completely breaks read():
 * write() suddenly returns the number of characters - instead of bytes -
 * written and read() just returns 0 as soon as a Unicode character is being
 * read.
 *
 * Therefore, instead of just using the UTF-8 codepage, this captures all reads
 * and writes to of_std{in,out,err} on the low level, interprets the buffer as
 * UTF-8 and converts to / from UTF-16 to use ReadConsoleW() / WriteConsoleW().
 * Doing so is safe, as the console only supports text anyway and thus it does
 * not matter if binary gets garbled by the conversion (e.g. because invalid
 * UTF-8 gets converted to U+FFFD).
 *
 * In order to not do this when redirecting input / output to a file (as the
 * file would then be read / written in the wrong encoding and break reading /
