My questions are as follows please.
Is that encoding for the Welsh flag included
in both The Unicode Standard and ISO/IEC 10646
or is it only encoded in The Unicode Standard
or is it in neither The Unicode Standard nor ISO/IEC 10646?
Neither.
A flag emoji is represented via a character sequence -- in this
particular case by an emoji tag sequence, as specified in UTS #51.
The representation of flag emoji via emoji tag sequences is *OUT OF
SCOPE* for both the Unicode Standard and for ISO/IEC 10646.
If you find that hard to understand, consider another example. The
spelling of the word "emoji" as the sequence of Unicode characters
<0065, 006D, 006F, 006A, 0069> is also *OUT OF SCOPE* for both the
Unicode Standard and for ISO/IEC 10646. Neither standard specifies
English spelling rules; nor does either standard specify flag emoji
"spelling rules".
Unless the answer is the first listed possibility, how does that work as
regards interoperability of sending and receiving a Welsh flag on an electronic
communication system?
One declares conformance to UTS #51 and declares the version of emoji
that one's application supports -- including the RGI (recommended for
general interchange) list of emoji one has input and display support
for. If the declaration states support for the flags of England,
Scotland, and Wales, then one must do so via the specified emoji tag
sequences. Your interoperability derives from that.
