How to load pango's engine module of specific language processing

[miaocheng <snopy-xj 163 com>]

  I use Redhat linux 8.0 . The version of Xfree86 is 4.0.3 and the desktop manag
e is Gnome .
  In my linux , locale variants , such as LANG and LC_ALL , is en_US.UTF-8 . I w
ant to input Arabic in this locale environment . I use XKB extension to input cor
rectly Arabic letters . But I can't load Pango's Arabic processing engine module 
, e.g pango-arabic-x.so or pango-arabic-xft.so, to reshape the inputed Arabic let
ters , so the Pango don't change the glyphs of inputed letters according to conte
xt and only one glyph always is showed .
   How can I load Arabic processing engine module in en_US.UTF-8's  locale envir
onment to reshape the inputed Arabic?
   Another question : I installed Redhat linux 9.0 in my another pc . I 
have selected Arabic support when I installed RH , and I use standard
ar_EG.UTF_8 
locales as setup by Red Hat's preference's langage selection tool  and 
also use XKB extension to input correctly Arabic letters . But  the 
pango's Arabic processing engine module is not available and don't 
reshape the inputed Arbic letters . where is the error.
Best regards,
The Arabic Keyboard map file of XKB I used is below.
xkb_keymap "myarabic" {
xkb_keycodes { include "xfree86" };
xkb_types { include "default" };
xkb_compatibility { include "default" };
xkb_geometry { include "pc(pc105)" };

xkb_symbols {

include "en_US(pc105)+group(toggle)"

name[Group1]= "US/ASCII";
name[Group2]= "Arabic";
