How did you get it to work. Are you just copying the en_GB file directly to the he_IL file? If so, and that's working, it may have simply been a case that the he_IL file you're using wasn't saved as UTF-8 for international characters (or that your server is having problems reading it). Just a thought as to how you may want to try saving any changes you made.
Hope you're good to go from here though!
