Enclosed CJK Letters and Months

Enclosed CJK Letters and Months is a Unicode block containing circled and parenthesized Katakana, Hangul, and CJK ideographs. Also included in the block are miscellaneous glyphs that would more likely fit in CJK Compatibility or Enclosed Alphanumerics: a few unit abbreviations, circled numbers from 21 to 50, and circled multiples of 10 from 10 to 80 enclosed in black squares (representing speed limit signs).

Not to be confused with Enclosed Ideographic Supplement, Enclosed Alphanumerics, or Enclosed Alphanumeric Supplement.

Note: [1][2]
In Unicode 1.0.1, during the process of unifying with ISO 10646, one character from the Enclosed CJK Letters and Months block was merged with an existing character in the CJK Symbols and Punctuation block, and the encircled katakana letters were re-arranged.[3]

Its block name in Unicode 1.0 was Enclosed CJK Letters and Ideographs.[4] As part of the process of unification with ISO 10646 for version 1.1, Unicode version 1.0.1 relocated the Japanese Industrial Standard Symbol from the code point U+32FF at the end of the block to U+3004, and re-arranged the encircled katakana letters (U+32D0–U+32FE) from iroha order to gojūon order.[3]

The Reiwa symbol (㋿) was added to Enclosed CJK Letters and Months in Unicode 12.1, continuing from the existing era symbols in the (fully allocated by that point) CJK Compatibility block (Meiji ㍾, Taishō ㍽, Shōwa ㍼, Heisei ㍻).

Emoji

The Enclosed CJK Letters and Months block contains two emoji: U+3297 and U+3299.[5][6]

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.[7]
