Ah, the joys of international characters I feel your pain. Unfortunately you don’t provide enough information to understand what’s happening and how to fix the issue. Did you write the script that runs in the cronjob task? Which emails exactly are prepared in Hebrew, by which application? Share exactly what you are trying to achieve, what happens and what you wish would happen. More details you share, more likely we are to understand what’s going on and provide ideas to fix it.
