We have gotten requests for this, but the stumbling block is the lack
of an official N. Ireland document describing what the official flag
is and should look like.
Such documents are lacking for several of the RIS flag emojis as well,
though, e.g. for 🇺🇲 from ISO 3166-1 code `UM` (United States
Outlying
Islands), resulting in unknown or duplicate flags, hence confusion.
The solution there would have been to exclude codes for dependent
territories becoming RGI emojis. ISO 3166 provides that property.
That's neither the problem nor the solution, IMHO. Even for RIS
sequences, you have no guarantee of exactly how the flag will be
depicted. For flags that have been recently changed, you might get the
old or the new. For UM, you might get the US flag or one of the
unofficially adopted flags. For Northern Ireland (if it were
RGI-blessed), you might get either the Ulster Banner or St. Patrick's
Saltire.
This situation is described, and explicitly so for the UM flags, in
Annex B of UTS #51 under "Caveats."
