As Marcia pointed out later in the process than I had time to work with, the vowels which were adapted for that typeface are an embarrassment. They were tacked on by me to a digitization of Adah that came with no vowels. The source came from a poor digitization of the marvelous Koren typeface. I ultimately redrew the vowels, but that came too late in the production process to incorporate into this book. Frankly, I was sloppy in part because I assumed that the vowels would be left off the display matter, as would be more common.
Vowels are a real problem with Hebrew.
They are, after all, small diacritical marks, usually below the affected letters, unobtrusive, and yet, interfering with the typesetter's craft and layout. In Yiddish, they are more commonly used, but only a couple are required on a couple of letters, so a Yiddish character set will often contain those few versions of letters attached to vowels as separate characters. A look at the work of Hebrew scribes reveals that most dashed off the vowels as an afterthought. For early printers, vowels were also painful. The small characters had to be painfully spaced under each line of Hebrew.
