What is the full range for Chinese characters in Unicode?

Question

U + 4E00..U + 9FFF is part of the set, but not all

Answer 1

Maybe you can find the full list in the CJK Unicode FAQ (which includes the characters "Chinese, Japanese, and Korean")

The East Asian Scenario document mentions:

Blocks containing han ideograms

Khan's ideographic symbols are found in the five main blocks of the Unicode standard, as shown in Table 12-2.

Table 12-2. Blocks containing han ideograms

Block Range Comment CJK Unified Ideographs 4E00-9FFF Common CJK Unified Ideographs Extension A 3400-4DBF Rare CJK Unified Ideographs Extension B 20000-2A6DF Rare, historic CJK Unified Ideographs Extension C 2A700–2B73F Rare, historic CJK Unified Ideographs Extension D 2B740–2B81F Uncommon, some in current use CJK Unified Ideographs Extension E 2B820–2CEAF Rare, historic CJK Compatibility Ideographs F900-FAFF Duplicates, unifiable variants, corporate characters CJK Compatibility Ideographs Supplement 2F800-2FA1F Unifiable variants 

Note: block ranges may change over time: the latter are in CJK's unified ideographies .

Answer 2

Unicode currently has 74,605 ​​CJK characters. CJK symbols include not only the symbols used by the Chinese, but also Japanese kanji, Korean Hanja, and Vietnamese Chu Nom . Some CJK characters are not Chinese characters.

1) 20941 characters from the Block of Unified Ideographers CJK .

Code points U + 4E00 to U + 9FCC.

• U + 4E00 - U + 62FF
• U + 6300 - U + 77FF
• U + 7800 - U + 8CFF
• U + 8D00 - U + 9FCC

2) 6582 characters from CJKUI Ext A block .

Code points U + 3400 to U + 4DB5 . Unicode 3.0 (1999).

3) 42,711 characters from the CJKUI Ext B block .

Code points U + 20,000 to U + 2A6D6. Unicode 3.1 (2001).

• U + 20,000 - U + 215FF
• U + 21600 - U + 230FF
• U + 23100 - U + 245FF
• U + 24600 - U + 260FF
• U + 26100 - U + 275FF
• U + 27600 - U + 290FF
• U + 29100 - U + 2A6DF

3) 4149 characters from the CJKUI Ext C block .

Code points U + 2A700 to U + 2B734 . Unicode 5.2 (2009).

4) 222 characters from the CJKUI Ext D block .

Code points U + 2B740 to U + 2B81D . Unicode 6.0 (2010).

5) Block CJKUI Ext E.

Answer 3

Exact ranges for Chinese characters (except extensions): [\u2E80-\u2FD5\u3190-\u319f\u3400-\u4DBF\u4E00-\u9FCC\uF900-\uFAAD] .

1. [\u2E80-\u2fd5]

The CJK Radical Supplement is a Unicode block containing alternative, often positional, forms of Kangxi radicals. They are used by headings in vocabulary indexes and other CJK ideographic collections organized by radical sweeping.

2. [\u3190-\u319f]

Kanbun is a Unicode block containing annotation characters used in Japanese copies of classic Chinese texts to indicate reading order.

3. [\u3400-\u4DBF]

CJK Unified Ideographs Extension-A is a Unicode block containing rare Han ideograms.

4. [\u4E00-\u9FCC]

CJK Unified Ideographs is a Unicode block containing the most common CJK ideographies used in modern Chinese and Japanese.

5. [\uF900-\uFAAD]

CJK compatibility ideographs are a Unicode block created to contain Han characters that have been encoded in several places in other installed character encodings, in addition to their CJK Unified Ideographs assignments, to maintain compatibility between Unicode and these encodings.

Answer 4

Unicode version 11.0.0

In Unicode, Chinese, Japanese, and Korean (CJK) scripts share a common framework known as CJK characters.

These ranges often contain unassigned or reserved code points (suck like U + 2E9A , U + 2EF4 - 2EFF)

• In the CJK Unified Ideographs block, I noticed that many answers use the 9FCC upper bound, but U + 9FCD (鿍) is indeed a Chinese character. And all the characters in this block are Chinese (also used in Japanese, Korean, etc.).
• Most of the characters in CJK Unified Ideograohs Ext (except Ext F, only 17% of Ext F are Chinese characters) are traditional Chinese characters that are rarely used in China.
• Form is a Chinese hieroglyphic form of scratch that is still in use today

Therefore the range

[0x3007,0x3007], [0x3400,0x4DBF], [0x4E00,0x9FEF], [0x20000,0x2EBFF]

CJK characters but never used in Chinese

They are ordinary khans used only for compatibility.

They are almost impossible to see in any Chinese book, article, letter, etc.

all characters here have one corresponding glyph-identical Chinese character. Like 金 (U + F90A) and 金 (U + 91D1), they are the same in Glyph.

• some blocks, such as the Hangul Compatibility Jamo, were abandoned due to a lack of relevance to the Chinese language.
• Kangxi Radicals are not Chinese characters, they are a graphic component of Chinese characters, they are used specifically to express the radicals .eg ⼻ (U + 2F3B) and 彳 (U + 5F73), ⻜ (U + 2EDC) and 飞 (U +) 98DE)

Another common punctuation appears in Chinese.

This is a wide range, some punctuation marks may never be used, some punctuation marks, such as ……"" , are so often used in Chinese.

There are also many Chinese-related symbols, such as the symbols of the hexagram Yijing or Kanbun, but this is off topic anyway. I am not writing Chinese characters in CJK to better explain what Chinese characters are. And the ranges above already cover almost all the characters in Chinese writing, except for mathematics and other special notation.

Answer 6

To summarize, it sounds like this:

 var blocks = [ [0x3400, 0x4DB5], [0x4E00, 0x62FF], [0x6300, 0x77FF], [0x7800, 0x8CFF], [0x8D00, 0x9FCC], [0x2e80, 0x2fd5], [0x3190, 0x319f], [0x3400, 0x4DBF], [0x4E00, 0x9FCC], [0xF900, 0xFAAD], [0x20000, 0x215FF], [0x21600, 0x230FF], [0x23100, 0x245FF], [0x24600, 0x260FF], [0x26100, 0x275FF], [0x27600, 0x290FF], [0x29100, 0x2A6DF], [0x2A700, 0x2B734], [0x2B740, 0x2B81D] ]
