Joel, I have noticed issues with Hebrew fonts. Few Word processors offer really great right to left Hebrew font support. Mellel is an exception (/). However, I think you might be able to fix your line spacing problem in Word by going to the “Format” menu, selecting “paragraph,” and changing the line spacing to “Exactly” and then entering the desired size of line spacing (., 12 point, 24 point, or whatever). This ought to make the line spacing consistent no matter the font used. Scrivener should be able to do similar formatting.
