The point is that you have to set up the otp filters to use the utf-8  
filter instead of the transcription filter. See below...

If you already have the regular omega support files in MiKTeX etc, then  
great. Otherwise:
Here is a set of instructions for ConTeXt users:

1. Get the omega support files:

http://www.ctan.org/get?fn=/systems/win32/fptex/0.7/package/omega.zip
http://www.ctan.org/get?fn=/systems/win32/fptex/0.7/package/omegafonts.zip

2. Get rid of the following directories from omega.zip (not really  
necessary but if u want to be efficient):

texmf/eomega
texmf/omega/encodings

3. Put files in texmf-local;

4. Compile the Aleph format:

mktexlsr

texexec --make en -tex=aleph

5. Always start aleph files with this preamble:

% tex=aleph output=dvipdfmx

Now test: texexec the following file (in utf-8). I have included a  
modified version of the one u already have for xtra practice-)

Study \def\ArabicUTF: it uses raw omega/aleph commands, but see also  
m-gamma.tex (in the ConTeXt distro) for some higher-level commands

\definefiltersynonym
\definefiltersequence
\usefiltersequence

Have fun!

Here's another file, similar to the one you started with:

% tex=aleph output=dvipdfmx
\input m-gamma.tex
\input type-omg.tex

\def\ArabicUTF{\ocp\UTFArUni=inutf8 %% in88596

                \ocp\CUniArab=cuni2oar

                \addbeforeocplist 1 \UTFArUni
                \addbeforeocplist 1 \UniCUni

                \nullocplist
