[XeTeX] Follow-up to previous mail about hyphenation

[Philip Taylor]

Not being an Arabist, I have no idea whether the output from the 
following is correct or not, but I thought that it would be fun to run 
Bruno's code on some 'real' Arabic rather than just on ^^^^ sequences —

% !TeX Program = Ini-XeTeX

\let \dump = \relax
\input xelatex.ini

      \language = 8 % how to do this better?
      \catcode "200D = 11
      \lccode "200D = "200D
      \patterns
          {
           ^^^^06431^^^^0643
           ^^^^200d1^^^^200d
          }
