Version Added - 12.1

12.1 is version in which a character was first introduced into Unicode, released in May 2019. This minor version was notable for adding only a single new character, the Japanese era name symbol for Reiwa (㋿), along with its corresponding variation sequence. Because Unicode typically avoids incrementing version numbers for such small additions, 12.1 stands out as a rare exception, created to meet the practical need for encoding the new era name promptly.
