Unicode Emoji 5.0 characters now final

[Peter Edberg]

(this time from the correct account)

Philippe and others,
http://www.unicode.org/reports/tr51/tr51-11.html#valid-emoji-tag-sequences <http://www.unicode.org/reports/tr51/tr51-11.html#valid-emoji-tag-sequences> refers to
CLDR data for the list of valid subregion sequences, see
http://unicode.org/reports/tr35/index.html#Validity <http://unicode.org/reports/tr35/index.html#Validity>

CLDR data will maintain stable sequences in the event that ISO 3166-2 data changes.

I think that the UTC should try contacting authors of Flags of the World and seek for advice there: we are speaking here about regional flags (we can exclude some graphical variants such as civil vs. navy flags vs honorific flags)

We just see that it's an ISO3166-1 country/territory code followed directly (without separator) by sequences of letter/digits, all of them converted to RIS and surrounded by a the same initial emeoji code and the DEL from RIS.
