Hi,All
I am porting Tiny-X to XScale platform,
When I want to display chinese, I meet some problem.
The following is my porting procedure.
I compile locale data using localedef(arm), put the locale data to
/usr/lib/locale/zh_CN
I put gconv.modules ,EUC-CN.so , libGB.so to /usr/lib/gconv
I edit locale.dir and locale.alias , add zh_CN.GB2312 support to these files
I put chinese font to /usr/X11R6/lib/X11/fonts/misc, and edit fonts.dir , fonts.alias
I export LC_ALL variable to zh_CN.GB2312 ,
Library I use is:
glibc-2.2.3.so
XFree86-4.20
BUT it can not display chinese,
following is my test program
setlocale(LC_ALL,"") is OK
XSupportsLocale() is OK
XSetLocaleModifiers(NULL) is OK
num = mbstowcs(wcstr,string,strlen(string)) is OK
XCreateFontSet(...) is OK
XmbDrawString(display,win,fontset,gc,50,100,string,strlen(string)); //display error
text(english is right, chinese is wrong)
XwcDrawString(display,win,fontset,gc,50,140,(wchar_t *)wcstr,num); //display error
text(english is right, chinese is wrong)
I wonder if XServer is wrong. Does Xserver need to set some options about locale when
It is compiled.
I wonder if xfs must run .
I am not sure whether It is locale problem or font problem.
Please help me to analyse this problem , What problem I could meet?
Thank you very much.
