This post describes how I have created matching Hebrew and Latin for my own font "Mike Hebrew".
I did not add this post to the "Creating a Merger of a Latin and a Non-Latin Font Style" because many of the replies did not deal with designing fonts. Furthermore don't want to be involved in criticizing other people's fonts, other people or to argue about history etc.
This design problem will be different for each kind of Hebrew font. If the Hebrew font is Frank Ruel then the solutions will be quite different to solutions that would be appropriate if the Hebrew font is Levenim. The is NO SINGLE SOLUTION.
What I write here only applies to matching the Hebrew and the Latin letters in my own "Mike Hebrew" font.
