See `(elisp) Word Motion':

     Characters that belong to different scripts (as defined by
     `char-syntax-table'), also define a word boundary

and discussion in Bug#10494 which prompted the update of that section.

Hmm, I think I meant `char-script-table', as `char-syntax-table' doesn't
seem to exist...
