For reasons I posted earlier, I don't think encoding the dot is the right approach.
I despair of following this thread.
I'd propose something that would look like this in the UCD (with 'nn' to be determined, but it should be in the Hebrew block):
05nn;HEBREW VOWEL HOLAM MALE;Lo;0;R;<compat> 05D5 05B9;;;;N;;;;;
We do not encode any HEBREW VOWELs. We encode LETTERs and combining marks. -- Michael Everson * * Everson Typography * * http://www.evertype.com
