Thread:User talk:CodeCat/"sc = None" and Latin script/reply (11)

Some sources has defined Zxxx as "Code for unwritten languages", this might be its previous standard definition. "Unwritten documents" has a broader meaning, and includes unwritten and reconstructed languages.

Agree about replacing "None" with "Zyyy" for languages that are written but we haven't gotten around to specifying them yet.

Also, as you mentioned, for Phaistos disc, signs have code points in Unicode but the writing system is undetermined and doesn't have an ISO code. If "coded" in the definition of Zzzz means "it has no encoding in Unicode", and not "it has no ISO code", then we need Zyyy ("undetermined script") for these signs.

Currently we are using Latin letters for terms in "Mani" and several others because they doesn't have code points in Unicode yet, I have always specified "sc" as "Latn" when I use Latin letters for these languages to avoid any possible displaying issues, but of course using their ISO codes is a better practice, shouldn't we do that? In this case, we should do some changes in detect_script by the way.

I think Zzzz means it has no ISO code, the word "coded" is not used to refer to Unicode encoding, is it? For Unicode encoding, I think they would write "not encoded" instead.
