Hey all!

I remember figuring this out a while ago, but I forgot since then...
under what conditions does WM_IME_CHAR return ascii question marks and not
the actual Unicode character. Does it have to do with _UNICODE not being
defined in the application?

And, which system is deciding to send the question mark? Is it the IME
itself, or some layer between my app and the IME?

It should never return ?.

Sounds like maybe you are expecting to see chars in the IDE even if they are
MBCS off the current default code page?

My program is MBCS and I will see "???" characters if I try to do a
Unicode->Multibyte conversion from a Double-Byte string(Japanesse) to an
English code page. But I have never seen WM_IME_CHAR return this.

I guess I am confused, then. I do not know of any circumstances that a
Unicode character will be returned as a question mark.

If you take a Japaneese Unicode string and do a WideCharToMultiByte function
call on an English locale you will get "????" back

Do you mean a code page like 1252? Yes, this is by design (and not a bug at
all).

I actually get the ASCII value for a question mark out of the IME through
WM_IME_CHAR.

For now, I'm avoiding the problem by getting my character from
ImmGetCompositionStringW.

Thanks, all!

I cannot repro the problem you describe -- and have just recently had
time/cause to be buried in these messages, for MSLU stuff. I never get a
question mark. Are you trying to convert something and failing?

Hey MichKa!

I basically didn't set up too much. I am working on code that is 3 or 4
years old and was not designed with localization in mind. The first change I
made was to add a WM_IME_CHAR section to our application's WndProc, and I
breakpointed the code. (I don't know if this matters, but I was not able to
define either UNICODE or _UNICODE because this broke things terribly)

Then, I ran the application in a window, pressed Alt-Shift to manually
bring up different IMEs and started typing away. When Windows had closed off
the composition window, my breakpoint got called with the ASCII question
mark (wParam is 63).

So, your guess is as good as mine =) I'm sure there's some setting
somewhere that's off.

Sounds like you are running on Win2000 or XP and are developing a
non-Unicode app?

This is by design and you should start handling the
WM_INPUTLANGCHANGEREQUEST message to refuse changes to these other input
locales.

And you should think about making a Unicode product, in the future... :-)
