Also, if @David_Chart weights on this, he should know that this is an offshoot on the Translating unknown glyphs using magic thread, in which it was argued whether, or not, that same guideline could be used to translate carvings into an unknown language, on the basis (If I understood correctly) that someone with appropriate skills (knowledge of the language in question) would be able to do that.
So this has repercussions far beyond the "fork" question
