CJK Compatibility is the name of a range of characters in the Unicode character encoding standard.

CJK squared Katakana words are Katakana-spelled words that fill a single display cell or em-square when intermixed with CJK ideographs. Likewise, squared Latin abbreviation symbols are designed to fill a single character position when mixed with CJK ideographs.

These characters are provided solely for compatibility with existing character encoding standards, including KS C 5601, CNS 11643 and various company registries. Modern software can supply an infinite repertoire of Kana-spelled words or squared abbreviations on the fly.

Japanese era names refer to these dates :

  • U+337B   ㍻  Heisei   1989-01-07 to present
  • U+337C   ㍼  Showa   1926-12-24 to 1989-01-06
  • U+337D   ㍽  Taisho   1912-07-29 to 1926-12-23
  • U+337E   ㍾  Meiji   1867 to 1912-07-28
Unicode's CJK Compatibility code block reserves the 256 code points from U+3300 to U+33FF, of which all 256 are currently assigned.

Enclosed CJK Letters and Months <-- CJK Compatibility --> CJK Unified Ideographs Extension A

Number of characters added in each version of the Unicode standard :
Unicode 1.1 : 249
Unicode 4.0 : 7

All the characters in this code block are in general category Symbol, Other So

Number of characters in each Bidirectional Category : 

Left To Right    L :249
Other Neutral   ON :  7

The columns below should be interpreted as :

  1. The Unicode code for the character
  2. The character in question
  3. The Unicode name for the character
  4. The Unicode Bidirectional Category for the character
  5. The Unicode version when this character was added

If the characters below show up poorly, or not at all, see Unicode Support for possible solutions.
