About Iso 10646-1, in src/encoding.C

[Hossein Noorikhah]

Hi
I don't know much about ISO-10646-1, I think it's somehow like unicode,  
but is developed by ISO; So I want to edit src/encoding.C file, and I want  
to know what are those constants used for the shapes of the arabic  
alphabets, as you can find in arabic_table, and arabic_table2.
If you know something, please help me. I couldn't find out what's  
happenning. I also tried to find some kind of table, for that, but I  
couldn't. If they were unicode constants, I could find them; But they are  
not, becuase they would be 2-byte, not 1-byte constants.
Thanks.
