Traditional Chinese (CP950) not displaying in WINE

[Anthony Fok]

Hello all,

We are experimenting some problems with displaying and inputting
Chinese characters in WINE (January 2002 or newer).  For example, most
Chinese characters show up as squares, and it seems that WINE doesn't
accept Chinese input via XCIN (an input method server using the XIM
protocol).  Did we misconfigured something?  Or is this a known problem
in WINE?  Any pointers would be appreciated.  Thanks!

Cheers,

Anthony

Probably some font misconfiguration problem. Apparently displaying of
Chinese characters should work since output of Japanese characters
admittedly works.

I'm afraid that correct input of Chinese and any multibyte characters
will require almost complete rewrite of the Wine keyboard code using
X Input Method/Input Context. Simultaneously it will solve the problem
with dead keys.

Unfortunately nobody worked on that problems yet. Do you want to try?

Thanks for your advice.  After tweaking the font settings ~/.wine/config,
we were able to get notepad to display Chinese text.  However, it seems to
only work with bitmap fonts like -taipei-*-; it had some problems with the
Arphic TrueType fonts that it seems Wine was using a different character set
to display the characters.  We'll do more investigation.  :-)

Yes, we are willing to give it a try.  How big a task is this?  Where should
we start?  Which files need to be modified?  (I am new to Wine, so any
starters/pointers would be helpful.)  :-)  Many thanks for your help!

Cheers,

Anthony

That's because truetype support has been only recently introduced and wasn't
cleaned up for all character sets yet. Apparently only people like you familiar
with problems of multibyte languages could enormously help in that area.

Good. :-)

I have made some tests and found that actually very little work is required:
create Input context using XOpenIM/XCreateIC. In order to not create context
for each window and therefore save some memory do attach windows to only one
global Input context in FocusIn event handler: XUnsetICFocus()/XSetICValues/
XSetICFocus(). Use XFilterEvent() to pass all work to an X server.

And don't forget to remove ugly dead keys emulating code from windows/message.c.

Hello,

I am sorry that I am newbie to Xlib, wine and xcin.  
I would like to ask if I should modify dlls/x11drv/x11drv_main.c,
in process_attach(), continue the call of TSXOpenIM(display, NULL, NULL, 
NULL);

XRegisterIMInstantiateCallback(...,im_callback,...);
 
and in my callback function:

im_callback()
{
  XOpenIM();
  ...
   XCreateIC();
}

as I know, we need to wrap X functions with wine_tsx11_lock() and
wine_tsx11_unlock(); Unfortunately I cannot find the IM API function
prototypes

e.g. XGetIMValues()

when I type "man XGetIMValues" it showed

~~~~~~~~~~~~~~~
XOpenIM(3X11)             XLIB FUNCTIONS            XOpenIM(3X11)

NAME
       XOpenIM, XCloseIM, XSetIMValues, XGetIMValues, XDisplay-
       OfIM, XLocaleOfIM, XRegisterIMInstantiateCallback, XUnreg-
       isterIMInstantiateCallback - open, close, and otain input
       method information

SYNTAX
       XIM XOpenIM(display, db, res_name, res_class)
             Display *display;
             XrmDatabase db;
             char *res_name;
             char *res_class;

       Status XCloseIM(im)
             XIM im;

       char * XSetIMValues(im, ...)
             XIM im;

       char * XGetIMValues(im, ...)
             XIM im;
...
~~~~~~~~~~~~~~


how can I know the details of the arguments? (sorry, maybe it's a Xlib 
question)

TSXGetIMValues(XIM im, ?????)
{
  wine_tsx11_lock();
  XGetIMValues(...);
  wine_tsx11_unlock(); 
}


and After my modifications, it does not work.
Could anybody help? Thanks very much!
(I attached x11drv_main.c that I modified)
