In Unicode 1.0.1, during the process of unifying with ISO 10646, the "IDEOGRAPHIC DITTO MARK" (仝) was unified with the unified ideograph at U+4EDD, allowing the Japanese Industrial Standard symbol to be moved from U+32FF in the Enclosed CJK Letters and Months block to the vacated code point at U+3004.[3]

CJK Symbols and Punctuation is a Unicode block containing symbols and punctuation used for writing the Chinese, Japanese and Korean languages. It also contains one Chinese character.

Block

The block has variation sequences defined for East Asian punctuation positional variants.[4][5] They use U+FE00 VARIATION SELECTOR-1 (VS01) and U+FE01 VARIATION SELECTOR-2 (VS02):

Variation sequences for punctuation alignment
U+ 3001 3002 Description
base code point 、 。
base + VS01 、︀ 。︀ corner-justified form
base + VS02 、︁ 。︁ centered form

Chinese character

The CJK Symbols and Punctuation block contains one Chinese character: U+3007 〇 IDEOGRAPHIC NUMBER ZERO. Although it is not covered under "Unified Ideographs", it is treated as a CJK character for all other intents and purposes.[6]

Emoji

The CJK Symbols and Punctuation block contains two emoji: U+3030 and U+303D.[7][8]

The block has four standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the two emoji, both of which default to a text presentation.[9]

Emoji variation sequences
U+ 3030 303D
base code point 〰 〽
base+VS15 (text) 〰︎ 〽︎
base+VS16 (emoji) 〰️ 〽️

History

In Unicode 1.0.1, two changes were made to this block in order to make Unicode 1.0.1 a proper subset of ISO 10646:[10][11][12]


The following Unicode-related documents record the purpose and process of defining specific characters in the CJK Symbols and Punctuation block:
