Hi, so while we don’t support RTL languages yet, you could convert your Illustrator lettering in Fontself and finish in another font editor.
Just rename each of your glyphs in the Fontself UI, or if you start from scratch rename each Illustrator object with their actual Hebraic character, and Batch import them in Fontself so they are automatically renamed properly.
But of course, when we fully support Hebrew (though in a long time at current pace 
) we will let you import custom sequences of characters in one go.
