Remember that "Phoenician" in this context includes Palaeo-Hebrew, an we *have* seen evidence that this script is mixed with Square in the same text, though not in the same word.
Remember that we have likewise seen Greek text with the Palaeo-Hebrew text embedded in it in exactly the same way, yet we do not propose to interfile Phoenician with Greek.
