Thanks to all for incorporating the new ISO country code (CQ = Sark) in CLDR v43

It's my understanding that the flag did not get added to RGI or was otherwise 
excluded from emoji data (otherwise it would follow Clipperton Island in 
emoji-sequences of https://www.unicode.org/Public/draft/emoji/ ).  I don't 
know if there's an official declaration on this or could come around in a 
future Unicode release, but wanted to note that it isn't in the 15.1 beta.

Regards,
Nick Doiron

In emoji-zwj-sequences.txt, the right-facing variants of Person Walking, Person Running, 
and Person Kneeling (+ their skin tone variants) have been placed in the “Other” 
category, but they should be in “Role”.

Two simplified/traditional variant issues in Unihan_Variants.txt 15.1 (also in 15.0):

# Unihan_Variants.txt
# Date: 2023-04-26 00:00:00 GMT [KL]
# Unicode version: 15.1.0

- currently:

U+2A2C8	kSimplifiedVariant	U+312C2
U+312C2	kTraditionalVariant	U+2A2C8

U+23D07	kSimplifiedVariant	U+3075C
U+3075C	kTraditionalVariant	U+23D07

- should be respectively "property-swapped":

U+2A2C8	kTraditionalVariant	U+312C2
U+312C2	kSimplifiedVariant	U+2A2C8

U+23D07	kTraditionalVariant	U+3075C
U+3075C	kSimplifiedVariant	U+23D07

In Chinese, there is a punctuation called 破折號, which is used
for "continuation of tone or sound, an abrupt change in thought, or adding
new content to the context". The current usage in Chinese is to use two
U+2014 EM DASH for this, but the two-em long dash should have side bearings
while connected in the middle, which normally two U+2014 EM DASH does not
fulfil both properties; it also allow mid-dash breaking which is not
allowed in Chinese typography. New font makers and typographers are slowly
transitioning to use U+2E3A TWO-EM DASH for this punctuation, including
Source Han ( https://github.com/adobe-fonts/source-han-sans,
https://github.com/adobe-fonts/source-han-serif) which included a CJK
version of this punctuation that is 2-em wide, has side bearings, and
vertically centered to Han ideographs.

1. It might be helpful to include a description under U+2E3A TWO-EM DASH for
Chinese usage as mentioned under W3C Requirements for Chinese Text Layout
(clreq) at https://www.w3.org/TR/clreq/ . Below is my suggestion for a
concise quote of usage to be put under U+2E3A:

• May be used in Chinese for abrupt change of thought, inserting new
  content, or continuation of tone or sound

2. I recognise the following decomposition isn't accurate, but it might also
be helpful to include its pseudo-decomposition used in Chinese as such:

≈ U+2014 U+2014

It can be done to the similar U+2E3B THREE-EM DASH too:

≈ U+2014 U+2014 U+2014

The following values seem to be incorrect:

㪳 (U+3AB3): kRSUnicode of 68.2 should be 68.1; kTotalStrokes of 6 should be 5
㫈 (U+3AC8): kRSUnicode of 70.6 should be 70.5; kTotalStrokes of 10 should be 9

Although these both have the nonstandard component of a circle (which I have 
assumed to be a single stroke), they should be compared with 㔔 (U+3514), which 
has a kRSUnicode of 19.4 and kTotalStrokes of 6 (i.e. the circle is counted as 
one stroke).

It seems that the newly-added U-source glyph UTC-02994 was wrongly 
unified to U+44D5 䓕.
With the addition of CJK Unified Ideographs Extension I in Unicode 15.1.0 Beta, 
I suggest that Unicode move UTC-02994 to U+2EDD4 𮷔, for the G-source glyph 
GIDC23-485 of U+2EDD4 𮷔 is identical to UTC-02994.
