Sure, although it can be close to okay with some backward and forward scanning but I'm nbot really in the mood for that now. Anyhow, for the occasional mix of arabic and latin this method works ok. For more extreme cases method 'one' will do and method 'two' ... well it depends on developments in unicode as this method will be the more configurable one. (And I can probably make a faster implementation of method two when performance matters.)
