您可以通过CJK Unicode FAQ（包括“中文，日文和韩文”字符）查找完整列表

“East Asian Script”文档的确提到：

  

包含汉字表意文字的块

     

汉字表意字符可在Unicode标准的五个主要块中找到，如   如表12-2所示

表12-2。含汉字表意文字的块

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

注意：块范围可以随着时间的推移而发展：最新版本在CJK Unified Ideographs。

Unicode version 11.0.0

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

These ranges often contain non-assigned or reserved code points(suck as U+2E9A , U+2EF4 - 2EFF),

Chinese characters

  • In CJK Unified Ideographs block, I notice many answers use upper bound 9FCC, but U+9FCD(鿍) is indeed a chinese char. And all characters in this block are Chinese characters(also used in Japanese or Korean etc.).
  • Most of characters in CJK Unified Ideograohs Ext (Except Ext F, only 17% in Ext F are chinese characters), are traditional chinese characters, which are rarely used in China.
  • 〇 is the chinese character form of zero and still in use today

Therefore the range is

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

CJK characters but never used in chinese

They are Common Han used only for compatibility.

It is almost impossible to see them appear in any chinese book, article , writings etc.

all characters here has one corresponding glyph-identical chinese characters. Such as 金(U+F90A) and 金(U+91D1), they are identical in Glyph.

  • some blocks such as Hangul Compatibility Jamo are abandoned because of no relation to Chinese.
  • Kangxi Radicals is not Chinese characters, it's graphical component of a Chinese charaters, it are used specially to express radicals, .e.g. ⼻(U+2F3B) and 彳(U+5F73), ⻜(U+2EDC) and 飞 (U+98DE)

Other common punctuation appears in chinese

This is a wide range, some punctuation maybe never used, some punctuations such as ……”“ are used so much in chinese.

……

There are also many chinese-related symbols, such as Yijing Hexagram Symbols or Kanbun, but it's off-topic anyway. I write non-chinese-characters in CJK to have a better explaination of what are chinese characters. And ranges above already covers almost all of chars appear in Chinese writing except math and other specialty notation.
