OSX Mavericks: Kotoeri Japanese input method sometimes appears to generate incorrect characters
When you have more than one input method selected in Mavericks, you may see one or more of the following:
- When Kotoeri and another language are both configured as keyboard input methods, the input source may not use JIS (Japan Industry Standards) keyboard settings as expected.
- OS X doesn't accept your screen saver password, even when it seems like you typed the password correctly.
In OS X Mavericks, Kotoeri uses the Latin keyboard layout at the prompts listed above when typing Japanese text. This causes differences in the keyboard layout when multiple languages are enabled as Input Sources. For example, if Kotoeri and French are both enabled as Input Sources, a Japanese keyboard registers the keypress of a “Q” key as an “A” instead.
To change this behavior, disable any additional languages besides Japanese from the Input Sources tab of Keyboard preferences in System Preferences.
