I tried to override the XftDrawString8() in Redhat 7.3 and I think I have a success. \
The HelloX.c which use XftDrawString8() to display a string have been modified \
(change into my own string) . But I also have some problems. And the biggest is " I \
can not override any string that I want in the  whole system ". I want to ask some \
question - VERY IMPORTANT and URGENT to me

1. What exactly Redhat 7.3 (XFree86 4.2, KDE 3.0, QT 3) functions use to display a \
string in the screen ?  I know that Xft have 4 functions : XftDrawString8(), \
XftDrawString16(), XftDrawString32(), XftDrawStringUft8() to display a string. And if \
the system uses Xft , it will call these functions. I tried to override all 4 \
functions . Compile OK but it can not work in my system. Maybe because of my poor \
programming skill in C or I must tried some Xlib functions

2. According to Xft document, it uses Unicode encoding for input string in Xft \
displaying functions, But it doesn't tell exactly what encoding ? : Uft8, Xchar2b, \
UCS2, UCS4 ( 16 or 32 bits )

3. C uses "wchar_t" for Unicode characters ? How to use it ? Can you send me some \
examples about using wchar_t functions ( wcscpy(),  wcscmp()....) . I have POOR \
programming skill. Please show me some tips, cuations when use these functions

4. Could we modify , configure  system (Xft )to automatically select the fonts to \
display a string which is best match to the original font in a text file. And how to \
do it ?

5.  I have a Microsoft Word document  which uses a Vietnamese font ( VNI-helvetica ). \
When I open it in Kword (Redhat 7.2) , Kword automatically change my original font ( \
VNI-helvetica) into (Helvetica - unicode font which available in my system) . Can you \
explain me this ? and tell me if I can hack the system to keep my original font in \
*.doc file, after that I change the font as I want.  
Dear , I know I bother you so much these days but I am in big TROUBLE. Time is not \
wait for me. Deadline coming... I have about 20 days to finish my project. There's \
alot to be done... I am sorry if you have to read my mail and answer such silly \
questions but all of your answers are very useful to me . Please help me for I can \
not find any one near me to help.  I'm sorry for my CC, It's so impolite  . Just \
forgive me .... Thank you for all things you've done to me ....and thanks for reading

I'm looking forward to seeing your reply.
