| Unicode version history | |
| 1.0.0 | 187 (+187) |
| 1.1 | 249 (+62) |
| 4.0 | 256 (+7) |
| Note: [1][2] | |
Characters U+337B through U+337E are the Japanese era symbols Heisei (㍻), Shōwa (㍼), Taishō (㍽) and Meiji (㍾) (also available in certain legacy sets, such as the "NEC special characters" extension for JIS X 0208, as included in Microsoft's version and later JIS X 0213).[3] The Reiwa era symbol (㋿) is in Enclosed CJK Letters and Months (the CJK Compatibility block having been fully allocated by the time of its commencement).
