U+43D5 䏕 ⿰月𡈼[G] ⿰⺼壬[T] ⿰月王[J] ⿰月壬[K]

should be changed to

U+43D5 䏕 ⿰月壬[GK] ⿰⺼𡈼[T] ⿰月王[J]

Also to say, the ⿰月王 glyph for Japan looks very suspicious (according to IPA 文字情報基盤, the pronunciation of the two unified variants are different), and that the TF glyph (⿰⺼𡈼) has displaced the more correct T4 glyph (⿰⺼壬) which is now in U+2F981.

The entry for 肯 is

U+80AF	肯	⿱止月[GJK]	⿱止月[TV]

Both the [GJK] and the [TV] decompositions are the same, so it could be simplified to

U+80AF	肯	⿱止月

The glyph for U+2BF4A 𫽊 has been changed from

⿰扌⿱龸子

to

⿰扌学

in the newest Code Charts.

U+25CA4 𥲤 ⿱竹虚
U+271FA 𧇺 ⿰光虛
U+27754 𧝔 ⿰衤虚[G] ⿰衤虛[T](control comparison)
U+27D06 𧴆 ⿰豸虛
U+28F0B 𨼋 ⿰阝虛
U+293E3 𩏣 ⿰虛韋
U+2955A 𩕚 ⿰虛頁
U+2B8DE 𫣞 ⿰亻虛

can be changed to:

U+25CA4 𥲤 ⿱竹虚[G] ⿰竹虚[TH]
U+271FA 𧇺 ⿰光虚[G] ⿰光虚[X]
U+27754 𧝔 ⿰衤虚[G] ⿰衤虛[T](control comparison)
U+27D06 𧴆 ⿰豸虚[G] ⿰豸虛[T]
U+28F0B 𨼋 ⿰阝虚[G] ⿰阝虛[TV]
U+293E3 𩏣 ⿰虚韋[G] ⿰虛韋[T]
U+2955A 𩕚 ⿰虛頁[T] ⿰虚頁[X]
U+2B8DE 𫣞 ⿰亻虛[V] ⿰亻虚[X]

The database contains:

U+808C  肌      ⿰月几[GTV]     ⿰⺼几[T]

The character is a japanese 常用漢字, and should have a japanese decomposition, which would likely be the former. The are other characters around this one that have the same kind of decompositions, where both side have a T decomposition, but no J. I wonder if they are typos, or if both decompositions actually are valid for T.

𧿋 (U+27FCB) should be ⿰ 𧾷 𡕒 instead of ⿰ 𧾷 㔿.

U+2170F 𡜏 ⿰女𣧄

By etymology, according to 説文解字, it should be a top/bottom character, not left right.
Suggested change:
⿱辝林 ⿱辝𣏟[X]

Wouldn't ⿻工从 be a better or more intuitive IDS for U+5DEB 巫 than ⿱一⿻丄从? For reference, Table I.1 of ISO/IEC 10646 Annex I uses ⿻从工 as the example IDS for U+2FFB ⿻, though I feel that ⿻工从 is more intuitive.

Add ⿰口忌

U+22001 𢀁 ⿰𣧄犮

Based on the original sources of U+22001 (T5-3776) (http://dict.variants.moe.edu.tw/variants/rbt/word_attribute.rbt?quote_code=QzAzMDMx):

字彙:

重訂直音篇:

𢀁 Pronunciation 魚乞切
𣧄 Pronunciation 魚乙切 / 魚乞切.

U+293A9 𩎩 ⿰韋⿻木𢎘
U+293A9 𩎩 ⿰韋&CDP-85C2;

should be

U+293A9 𩎩 ⿰韋𣎺

U+7690 皐 ⿱白𠦂

is more correctly

U+7690 皐 ⿱白𠦂[GHV] ⿱白⿻十⿰二二[TJK]

This does not affect any character containing U+7690, except for the following.

U+22FCE 𢿎 ⿰皐攴

The T-source of this character the last stroke on the left bends leftwards.

U+3828 㠨 is listed as ⿱山欝 but unless I'm mistaken it appears that it should be ⿰山欝.

The IDSes for U+3514 㔔, U+3AB3 㪳, and U+3AC8 㫈 use U+3007 〇 as its component, but U+3007 has numeric properties, and is suitable as a component only in shape.

Instead, consider replacing it with CJK Stroke U+31E3, which has no numeric properties, and corresponds to a syllable-final ng/ŋ sound that is related to the shape of U+11BC HANGUL JONGSEONG IEUNG (combining) or U+3147 ㅇ HANGUL LETTER IEUNG (compatibility).

朩 is an Idu character which is actually the cursive form of 木, so they are semantically equivalent from a CJK Unified Ideographs point of view. Also, characters with 木 in Taiwan are usually written as 朩 without the hook when placed at the bottom. Separating them causes difficulty in lookup.

Suggested Options:
(1) Merge all 朩 without the hook into 木.
(2) Merge all 朩 with or without the hook into 木.

I prefer Option (1), because Option (2) may confuse users in China.

If no change is made, then the following rules should be added:

U+217fd 𡟽 should be ⿰女𡋲

U+205B8	𠖸	⿰ 冫 ⿱ &CDP-8AFC;() 匕

is actually

U+205B8	𠖸	⿰冫仺

By etymology,
仺 = 倉
𠖸 = 滄

Therefore, the separation of strokes and the presence of final 鉤 need not be counted as different component.

U+226B9 𢚹 ⿰忄𣅘

To follow the V glyph (and also more correct etymologically 𢚹 = 忄 + 𣅘)

It currently is

⿰扌步[GTK]	⿰扌歩[J]

But the 常用漢字表 explicitly says the form for that character doesn't match that of 歩, so it seems it should simply be

⿰扌步

(Although my electronic version of the 漢字源 dictionary, which is older than 2010, does show the extra stroke)

U+443D  䐽  ⿰⺼⿱廿兩[T]  ⿰月⿱廿兩[K]  ⿰月㒼[X]

to

U+443D  䐽  ⿰月⿱㒼[G]  ⿰⺼⿱㒼[T]  ⿰月⿱廿兩[K]

U+5FF9	忹	⿰忄王[G]	⿰忄壬[T]

should be

U+5FF9	忹	⿰忄王

I am a big fan of this library and I have been using it for personal purposes a lot, but I am considering using small parts of the data in a paper to illustrate how Chinese character evolution could be modeled. I could quote this library by just passing the github link, however, I'd prefer if you share how you like to be quoted explicitly, so that you get the credit you deserve. Furthermore, I'd suggest that you make a release of the data, and that you also submit this release to some open repository like Zenodo.org, so that we can quote you correctly, with a DOI for a particular version that is being used in research (non-profit, of course).

Hi. I'm not sure that this is the right place to report this. I was using Atom factoids plugin (which uses the data from this repo) and noticed that 雨 is decomposed as ⿱一𠕒 and this looks very strange to me.
I'm not a specialist in this stuff, so probably it's correct.

The component would be &hkcs-comp-0001;
Glyph of component would be http://en.glyphwiki.org/glyph/hkcs_comp-0001.svg

U+9A3A 騺 ⿱執馬[GT] ⿱埶馬[K]

would now be

U+9A3A 騺 ⿱執馬

in the latest code charts.

U+2B2D1	𫋑	⿰虫⿲王㐅王

should be changed to

U+2B2D1	𫋑	⿰虫班

Reference:

The 𫋑 has a semantic component 虫 and phono component 班.

U+21D2C 𡴬 ⿰𡴤𡴤

Additional Decomposition ⿱𠦔貝 which is the semantical decomposition

U+2468C 𤚌 ⿸尸⿱⿰二⿺乚二牛

to

U+2468C 𤚌 ⿸㞑牛

Also refer to:

U+21CB6 𡲶 ⿸㞑出

Some of them decompose using 曰, some of them decompose using 日, some of them decompose using both. I think at least some of the ones using 日 should also have a decomposition using 曰 (at least
更, 最, 書, 曹, 曽, 替, for those I know)

U+21CF2 | 𡳲 | ⿺尾⿱爫萬

should be

U+21CF2 | 𡳲 | ⿺尾⿱爫禺

It currently is:

⿰彳⿱幺夊

I think there should at least be this variant:

⿰彳⿱幺夂[J]

Note there is precedent in characters like 夏, 憂, 致, 𢖻

They are:

U+7948	祈	⿰礻斤[GT]	⿰示斤[JK]
U+7949	祉	⿰礻止[GT]	⿰示止[JK]

I think they should be:

U+7948	祈	⿰礻斤[GTJ]	⿰示斤[K]
U+7949	祉	⿰礻止[GTJ]	⿰示止[K]

The reason is that while there are 旧字体 with the 示 form, their form in the 常用漢字表 is with 礻.
Plus, the variants with 示 now have their own codepoints: U+FA4E (祈) and U+FA4D (祉)

It is

⿰口臭

but it should arguably be

⿰口臭

U+27627 𧘧 ⿰ 衤 ⿱ 丿 &CDP-85F1;()

should be

U+27627 𧘧 ⿰衤𤣫

where 𤣫 is a variant of 斗 and 𧘧 a variant of 𧘞

Additional decomposition ⿱𢍏豕 which is the logical decomposition following 豢 from 說文

U+28599 𨖙    ⿺辶眾   ⿺辶衆

is more accurately

U+28599 𨖙    ⿺辶眾[T]    ⿺辶⿱⿱丿罒&CDP-8C76;[V] ⿺辶衆[X]

U+2378C 𣞌    ⿰木⿱⿱白冖⿱太万

Should be

U+2378C 𣞌    ⿰木⿱⿱白冖⿱大方

This is evident with the T-source glyph (TF-5F2D). In T-source glyphs containing 太, the dot is always joined with 大. Also, for glyphs containing 方, the dot is always joined with 万. In this case since the dot is joined with 万, it can be deducted that the correct decomposition is 大方.

This is also reflected in CNS11643's decomposition at
http://www.cns11643.gov.tw/AIDB/query_general_view.do?page=f&code=5f2d:
木白冖大亠&cdp-8b6c

The Kang Xi radical code for 為 is for 灬, so at the very least, it seems the IDS for it should be:

⿱⑤灬

More generally, there seems to be a few characters with no decomposition that should at least be decomposed into some IDC + some number + their 部首, where both the number and the 部首 can be derived from the kRSKangXi information from the UniHan DB... (although in some cases, kRSAdobe_Japan1_6 and/or kRSUnicode can have different values, but I'm not sure if that's the case for the characters that currently have no decomposition)

I guess I could run a script to cross-check the UniHan DB vs. the characters in the idx.txt file that have the same thing in both columns 2 and 3 (i.e. have no decomposition).

IDS for 𧆪 should include 𠂞 (u2009e) according to etymology

Additional IDS as:
| U+291DE | 𩇞 | ⿰青炁 |

𩇞 is the variant form of 靝 (天), and 炁 is the variant form of 氣 (qi4). 旡 (ji4) is the phonetic element of 炁, it is unrelated to the similar glyph 无 which is simple form of 無.

U+2AF18 𪼘 ⿰王⿱𫇦亘

should be

U+2AF18 𪼘 ⿰王萱

U+26E8C | 𦺌 | ⿱艹⿰氵⿳穴人夂[U]⿱艹⿰氵⿳穴人又[GT]

change to

U+26E8C | 𦺌 | ⿱艹𣸈

U+27C9D	𧲝	⿱䘙豚

should be

U+27C9D	𧲝	⿱衞豚[G]	⿱衛豚[T]

Additionally,

U+27C9E	𧲞	⿱䘙𧱔

should be

U+27C9E	𧲞	⿱衞𧱔[G]	⿱衛𧱔[T]

Edits: U+27C9E is 𧲞 instead of 𧲝, though the decomposition is correct.

U+2189B	𡢛	⿱⿲幺⿱丿幺幺𡚴[G]	⿱𪺕𡚴[T]

should be changed to

U+2189B	𡢛	⿱⿲幺⿱丿幺幺𡚴[G]	⿳丿⿲幺幺幺𡚴[T]

U+9269	鉩	⿰金尒[GJK]  ⿰金𡭗[T]

should be

U+9269	鉩	⿰金尒

U+2C606	𬘆	⿰ 糹 ⿻ 申 ⿱ 𠔽 月 ⿰ 糹 ⑭

should be

U+2C606	𬘆	⿰ 糹𤲥

instead.

Reference:

U+2A9A7	𪦧	⿰ 女 𤲥

Suggest add IDS for U+2011A 𠄚 ⿰𠀭丁[X]

𠄚 in Kangxi:

𠄚 in Jiyun:

It is likely that Kangxi mis-copied the form again. 𠀭 is old form of 平, and based on the description of Kangxi and the arrangement of 𠄚 in Jiyun, 𠄚 is likely old form of 𢆊, so the left hand side should theoretically be 𠀭.
