Big tech warns of 'Japan's millennium bug' ahead of Akihito's abdication


The Japanese calendar counts up from the coronation of a new emperor, using not the name of the emperor, but the name of the era they herald. Akihito’s coronation in January 1989 marked the beginning of the Heisei era, and the end of the Shōwa era that preceded him; and Naruhito’s coronation will itself mark another new era. 

It means that most software has not been tested to ensure that it will behave with an additional era. Also, Japanese computers use one character to represent the entire era name (compressing Heisei into ㍻ rather than 平成, for instance), Unicode needs to set the standard for that new character.

Update 21 Aug - The new name will be encoded at U+32FF. Companies in font space will have to work to ensure the new character is supported and any word processing software will have to ensure that the same is interpreted and displayed properly.
