    May be you would find a complete list through the CJK Unicode FAQ (which does include "Chinese, Japanese, and Korean" characters)

    The "East Asian Script" document does mention:

    Blocks Containing Han Ideographs

    Han ideographic characters are found in five main blocks of the Unicode Standard, as shown in Table 12-2

    Table 12-2. Blocks Containing Han Ideographs

    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: the block ranges can evolve over time: latest is in CJK Unified Ideographs.

    Unicode currently has 74605 CJK characters. CJK characters not only includes characters used by Chinese, but also Japanese Kanji, Korean Hanja, and Vietnamese Chu Nom. Some CJK characters are not Chinese characters.

    1) 20941 characters from the CJK Unified Ideographs block.

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

    1. U+4E00 - U+62FF
    2. U+6300 - U+77FF
    3. U+7800 - U+8CFF
    4. U+8D00 - U+9FCC

    2) 6582 characters from the CJKUI Ext A block.

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

    3) 42711 characters from the CJKUI Ext B block.

    Code points U+20000 to U+2A6D6. Unicode 3.1 (2001).

    1. U+20000 - U+215FF
    2. U+21600 - U+230FF
    3. U+23100 - U+245FF
    4. U+24600 - U+260FF
    5. U+26100 - U+275FF
    6. U+27600 - U+290FF
    7. 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) CJKUI Ext E block.

    Coming soon

    If the above is not spaghetti enough, take a look at known issues. Have fun =)

    The Unicode code blocks that the others answers gave certainly cover most of the Chinese Unicode characters, but check out some of these other code blocks, too.

    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(such 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.

    The exact ranges for Chinese characters (except the extensions) are [\u2E80-\u2FD5\u3190-\u319f\u3400-\u4DBF\u4E00-\u9FCC\uF900-\uFAAD].

    1. [\u2e80-\u2fd5]

    CJK Radicals Supplement is a Unicode block containing alternative, often positional, forms of the Kangxi radicals. They are used headers in dictionary indices and other CJK ideograph collections organized by radical-stroke.

    1. [\u3190-\u319f]

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

    1. [\u3400-\u4DBF]

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

    1. [\u4E00-\u9FCC]

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

    1. [\uF900-\uFAAD]

    CJK Compatibility Ideographs is a Unicode block created to contain Han characters that were encoded in multiple locations in other established character encodings, in addition to their CJK Unified Ideographs assignments, in order to retain round-trip compatibility between Unicode and those encodings.

    For the details please refer to here, and the extensions are provided in other answers.

    To summarize, it sounds like these are them:

    var blocks = [
