# This code is kind of a big hack. We want to support a special form of name of
# Allah, but the sequence <Alef><Lam><Lam><Heh> can occur in many unrelated
# words, showing the special form for those wards is very confusing and can
# even be offending to some people. Thus we define explicit contexts,
# including Tashkil marks that can't but be the name of Allah and ignore the
# special form for any other occurrences, but this is far from being simple.
#
# The first calt substitutes any [<Alef>]<Lam><Lam><Heh> preceded by a letter
# that is known not to be part of any of the allowed words by a regular non
# special form. The next block will then substitute the allowed context, given
# it meets a certain criteria.
#
# The idea originated from this forum thread:
# http://www.graphics4arab.com/showthread.php?t=3975
# and I just adapted it for Amiri, credit where credit is due.
