"Excerpt Options" can't count Arabic words!! please solve quickly

I have already got the paid Fabulous Fluid Pro, but today I noticed a big problem there! In the option "Excerpt Options / Excerpt Length (words)" I notice that the theme count just when the text is in latine words. So my text in arabic letter cannot counted and so I must set the "Excerpt Length (words)" to ZERO and but an english word at the position I want to cut! Check it here: http://www.ecuatouring.com/ar/ This is really too bad and not nice. I know that it can work also with the arabic or other letter. I saw that in other themes. So please let the developer solve this big problem.
