Kotoeri

Kotoeri (ことえり or 言選り), formerly Turbo Japanese Input Method or TurboJIP, was an marketed by Apple Computer to support Japanese characters in classic Mac OS and early versions of Mac OS X for Macintosh computers sold in Japan.

History
KanjiTalk, a version of classic Mac OS, was originally developed by Apple’s Pacific division, led by Dave Kleinberg with Mark Davis and Ken Krugler as its software architects. It was released with the Japanese version of the Macintosh Plus in May 1986. Krugler then left Apple to found TransPac Software, which developed KanjiTalk 2.0 for Apple. Released in February 1988, KanjiTalk 2.0 introduced TurboJIP as its input method.

KanjiTalk 7.1 was released in October 1992, which introduced WorldScript, co-authored by Mark Davis to unify the encoding of foreign language characters. TurboJIP became Kotoeri, the default input method adopted by KanjiTalk 7.1 and later. KanjiTalk support in a modified version of Mac OS 7.5.2 was used in many Pippin games released in Japan. However, support for added about half of a megabyte to system memory requirements. Some third-party applications used EGBRIDGE as a Japanese input method instead of Kotoeri.

The features of Kotoeri were absorbed into WorldScript's Japanese Language Kit and became a standard part of Mac OS 8.5, which was released in 1998. WorldScript was superseded by Unicode support, which is integrated into all versions of Mac OS X. Only the Kotoeri input method remained in name, until the release of OS X 10.10 Yosemite. A major bug in the transition was supposedly fixed in version 10.10.2.
