Table 12-38 is missing a couple of space characters, namely in “0D310D31” and “0D2A0D31”.

I would also note in passing that it is somewhat jarring to note just how
many ways there are of formatting sequences in this chapter: Table 12-32
lists code points separated by commas in angle brackets, Table 12-35 lists
code points separated by commas with no angle brackets, Table 12-37 lists
code points interspersed with descriptions, Tables 12-38 and 12-39
list code points separated by spaces, and Table 12-40 has parallel lists of
descriptions and code points separated by commas. While I would not assume
a single format is best for every purpose, it does seem that there could be
more consistency in this chapter at least.

Opt Subject: Bamum Supplement Block [SEW]

this concerns seemingly faulty character names in the Bamum Supplement
Block. Presuming that the phonetic readings (that served as the basis for
the character names) as given in the underlying proposal (N3597, L2/09-102
with N3523, L2/09-106) are correct and following the conventions specified
therein (on p. 3), there are seemingly typos in the following character
names:

1680B "MAEMBGBIEE" for MAEMGBIEE (məmgbie)
16881 "PUNGAAM" for PUNGGAAM (puŋgaam)
1688E "NGOM" for NGGOM (ŋgɔm)
168DC "SETFON" for SHETFON (ʃɛtfɔn)
16963 "MBAA SEVEN" for SAMBA (samba)
1697D "NGOP" for NGGOP (ŋgɔp).

For two further characters, 16839 FIRI ("firʼi") and 16A24 NI ("nʼi"), the
phonetic source form contains an apostrophe, for which however no
conversion is indicated. Might those not be either, resp., FIR-I and N-I,
or, if the apostrophe is a variant for ʔ, FIRQI and NQI?

Note that, writing from Germany, I myself can't actually read the script nor
speak the underlying language and have no connections to the user
community. I merely noticed discrepancies between the columns (phonetic vs.
en vs. fr) in the indicated proposal (pp.21 ff.).

Eric Muller noticed that TUS table 4-5 shows U+5146 with the value 1,000,000,000,000 (10,000 × 10,000 × 10,000)
which since Unicode 15.1 is no longer the Numeric_Value of that code point.

See

https://www.unicode.org/Public/15.0.0/ucd/extracted/DerivedNumericValues.txt 
https://www.unicode.org/Public/15.1.0/ucd/extracted/DerivedNumericValues.txt 

The kPrimaryNumeric value is
1000000 1000000000000
(with two values separated by a space).
The first one of these is the Numeric_Value.

Also, kPrimaryNumeric has data for 20 code points, while table 4-5 shows only 17.

DoNotEmit.txt: Add to “Discouraged” or “Preferred spelling” decomposition of
those Cyrillic letter known by me:

Ёё Йй Ўў

(Cyrillic capital/small letter Io, Cyrillic capital/small letter Short I,
Cyrillic capital/small letter Short U)

e.g.
0415 0308 → 0401   # Cyrillic capital letter Ie + combining diaeresis → Cyrillic capital letter Io

Maybe others, but I don’t know.

Її (Cyrillic capital/small letter Yi) is tricky and IDK what to do:
discouraged in decomposed form in modern Ukrainian text, but maybe allowed
in Old Slavonic.

Rationale: most Cyrillic fonts do not lay combining marks properly, and
common breve has other shape different from Cyrillic. And these four
letters in modern shape are really distinct entities.

Note: This report duplicates report #ID20240112220043 filed against PRI #489, and will be handled there.

DoNotEmit.txt currently includes the following line:

0149; 02BC 006E; Deprecated # LATIN SMALL LETTER N PRECEDED BY APOSTROPHE; MODIFIER LETTER APOSTROPHE, LATIN SMALL LETTER N

The character in question, U+0149 LATIN SMALL LETTER N PRECEDED BY
APOSTROPHE, has had the Deprecated property since Unicode 5.2.0. According
to L2/08-287, the character was deprecated because its decomposition used
the wrong apostrophe character: RIGHT SINGLE QUOTATION MARK is the
preferred character for Afrikaans, not MODIFIER LETTER APOSTROPHE.

The line in DoNotEmit.txt should use the preferred string instead of
U+0149's compatibility decomposition. The line should be changed to:

0149; 2019 006E; Deprecated # LATIN SMALL LETTER N PRECEDED BY APOSTROPHE; RIGHT SINGLE QUOTATION MARK, LATIN SMALL LETTER N

I propose adding Duployan (Dupl) to the Script_Extensions for the following
code points based on annotations in the names list for the Duployan block,
the contents of UTN #37, “Duployan Shorthand”, and the original encoding
proposal for Duployan, L2/10-272r2:

	U+00B7 MIDDLE DOT
	U+0300 COMBINING GRAVE ACCENT
	U+0301 COMBINING ACUTE ACCENT
	U+0304 COMBINING MACRON
	U+0306 COMBINING BREVE
	U+0307 COMBINING DOT ABOVE
	U+0308 COMBINING DIAERESIS
	U+030A COMBINING RING ABOVE
	U+0323 COMBINING DOT BELOW
	U+0324 COMBINING DIAERESIS BELOW
	U+0331 COMBINING MACRON BELOW
	U+2E3C STENOGRAPHIC FULL STOP

Duployan for Romanian also makes use of U+00B0 DEGREE SIGN in numerical
contexts, though as this character is in common use in a variety of writing
systems and has no explicit Script_Extensions as of now there would likely
be little benefit to specifically listing just Duployan.

However, section 11.4.3 of the core spec specifically states:

»For example, U+13217 𓈗 EGYPTIAN HIEROGLYPH N035A apparently could
 be represented by the sequence <13216, 13430, 13216, 13430,
 13216>. However, this compound sign is considered a single
 entity in Ancient Egyptian by Egyptologists, because the compound
 sign conveys a function that is not covered by the meaning of its
 individual parts. As a result, the atomic character U+13217 should
 be used.«

I do not know which representation is actually the preferred one, so either
this DoNotEmit entry or this section of the core spec should be removed.

However, the paragraph in question actually uses a paragraph separator, not a 
line separator. `</p>` should be replaced with `</br>` in the HTML.

Unicode 16.0 will have 5 characters with Indic syllabic category
Consonant_Preceding_Repha. Such characters represent non-spacing marks, but
are encoded in phonetic order before the consonant on top of which they’re
rendered, and therefore have general category Lo.

The representative glyphs for such characters in the code charts and, where
shown, in the core specification have an enclosing dashed box to reflect
their unusual properties.

There’s an inconsistency in what’s shown inside that box: Most
representative glyphs show the repha glyph by itself, but the one for
Tulu-Tigalari shows the repha glyph on top of a dotted circle.

I think showing the repha mark on top of a dotted circle actually makes
sense.

Affected characters:
0D4E ; Consonant_Preceding_Repha # Lo MALAYALAM LETTER DOT REPH
113D1 ; Consonant_Preceding_Repha # Lo TULU-TIGALARI REPHA
11941 ; Consonant_Preceding_Repha # Lo DIVES AKURU INITIAL RA
11D46 ; Consonant_Preceding_Repha # Lo MASARAM GONDI REPHA
11F02 ; Consonant_Preceding_Repha # Lo KAWI SIGN REPHA

The Do Not Emit data file contains the following lines.

---
ب ٔ; ࢡ; Hamza_Form # ARABIC LETTER BEH, ARABIC HAMZA ABOVE; ARABIC LETTER BEH WITH HAMZA ABOVE
ح ٔ; ځ; Hamza_Form # ARABIC LETTER HAH, ARABIC HAMZA ABOVE; ARABIC LETTER HAH WITH HAMZA ABOVE
ر ٔ; ݬ; Hamza_Form # ARABIC LETTER REH, ARABIC HAMZA ABOVE; ARABIC LETTER REH WITH HAMZA ABOVE
---

These mappings are valid for orthographies that use the atomic character as
a letter of the alphabet, but they are not appropriate for Kashmiri, which
uses the hamza as a vowel diacritic, not as an ijam.

See
https://r12a.github.io/scripts/arab/ks.html#non_canonical 
https://r12a.github.io/scripts/arab/homographs.html#nehomographs 

Although the hamza is not a tashkil, the distinction made here follows the
logic in the standard related to ijam vs tashkil usage. See
https://r12a.github.io/scripts/arab/homographs.html#ijam_tashkil 

Having special rules for just a few, arbitrary combinations of hamza and
base in Kashmiri is likely not only to lead to inconsistency in encoding,
leading to failures in searching and other operations, but it is also a
recipe for confusion for users. Note that all other uses of the vowel hamza
above a base character in Kashmiri have no corresponding ijam (and if
there's a possibility that atomic characters for these pairings may be
created for other languages in the future this adds further complexity).

It seems to me that one solution to this would be to add some sort of
qualification, by language, for these entries. Or perhaps it would be
helpful to make these combinations canonically equivalent and remove them
from Do Not Emit.  Users would then be able to type the items either way,
and end up with compatible text.
