  16 // input/output keydown/keyup events; it assumes that things don't work like
  17 // Windows does. When it gets a keydown event, it then tries to insert a
  18 // character at the same time.
  19 //
  20 // However, we're standardizing on Windows' WM_CHAR style events. This tries to
  21 // follow InputMethodWin::DispatchKeyEvent() instead, because PlatformViewX11
  22 // now synthesizes a character events so that we have one behaviour across our
  23 // platforms.
