- /* The problem that this code attempts to work around is that the
- * console-mode input routines are broken on Windows 95 if you're
- * using dead keys. A dead key is an accent key, such as acute,
- * grave, or umlaut, that doesn't produce a character by itself,
- * but when followed by another key, produces an accented character,
- * such as a-acute, e-grave, u-umlaut, n-tilde, and so on. Very
- * useful for most European languages. English-language keyboard
- * layouts don't use dead keys, as far as I know.
- *
- * Unfortunately, the KEY_EVENT_RECORD contains the wrong data when
- * I get the keystroke that's supposed to have an accented character.
- * The AsciiChar part contains the unaccented character instead.
- *
- * The following code (unsuccessfully) attempts to fake the dead keys.
- * I rely on the fact that the virtual key code and the scan key code
- * are actually correct for both the dead key and the following letter.
- * I set up a second thread that creates a hidden window and then sits
- * in a little message loop. I send it all the data from the dead key
- * and the following key (each thread has its own keyboard input state),
- * and it sends its own hidden window a suitable sequence of WM_KEYDOWN
- * and WM_KEYUP messages. TranslateMessage causes these to be turned
- * into WM_DEADCHAR and WM_CHAR messages. Almost. It works as long as
- * neither the dead key nor the following key are shifted, but after
- * happens, that it goes to hell in a handbasket.
- *
- * I have spent many, many hours trying all sorts of approaches to get
- * dead keys to work with Windows 95 and I am completely stumped.
- *
- * So why not just have all the input come directly via WM_CHAR?
- * Because this is a console application and I don't know how to do that.
- *
- * So how do you type dead keys? Answer: you don't, not if you're using
- * Windows 95, not until either Microsoft fixes the bug (and they haven't
- * as of Service Pack 1) or someone (me?) produces a true Windows GUI
- * version of Vim.
- *
- * If someone can come up with some workaround, please, please, please
- * send it to me.
- *
- * You can, however, use digraphs. They're not as convenient as dead
- * keys, especially if you're used to typing dead keys, but they do
- * work and they're better than nothing.
- *
- * If you're using NT, the dead keys work fine. At least they do with
- * NT 3.51, Service Pack 3, US Edition. I haven't tested it with any
- * other version of NT. I did hear one report that NT3.51, SP3, UK edition
- * had problems with CTRL-vowels, but I don't know about dead keys.
- *
- * /George V. Reilly, 3/15/1996
- *
- * On 24th March, I was told by a senior developer at Microsoft:
- * Win95 console support has always been and will always be flaky.
- *
- * The flakiness is unavoidable because we are stuck between the world of
- * MS-DOS keyboard TSRs like KEYB (which wants to cook the data; important
- * for international) and the world of Win32.
- *
- * So keys that don't "exist" in MS-DOS land (like dead keys) have a
- * very tenuous existence in Win32 console land. Keys that act
- * differently between MS-DOS land and Win32 console land (like capslock)
- * will act flaky.
- *
- * Don't even *mention* the problems with multiple language keyboard
- * layouts...
