Notes on secondary languages when you require English as the primary language

If you install Japanese DBCS (feature number 5762) as a secondary language and you require English as a primary language

If you install Japanese DBCS (feature number 5762) as a secondary language and you require English as a primary language, you should install English uppercase DBCS (2938) as the primary language. English uppercase DBCS (2938) should be installed because all of its user interface text is in uppercase English letters. Some Japanese workstation displays do not support lowercase English letters. English Uppercase DBCS allows users to view English text from these Japanese displays, without loss of data. If you do install English uppercase DBCS as the primary language, you must respond to all messages in uppercase rather than lowercase. If you respond in lowercase, you will receive an error message.

Set the QKBDTYPE system value to JUB (Japanese English) when using Japanese DBCS (5762) as a secondary language with English Uppercase and Lowercase Support for DBCS (2984). Use JUB as QKBDTYPE because this allows the primary language users to enter English characters, but not Katakana characters.

If Simplified Chinese, Traditional Chinese, or Korean is used as a secondary language and English is required as the primary language

If Simplified Chinese, Traditional Chinese, or Korean is used as a secondary language and English is required as the primary language, use English Uppercase and Lowercase (2984) as a primary language. You should use English Uppercase and Lowercase because English uppercase and lowercase characters can be displayed on devices supporting these DBCS languages.

In other cases:

In cases other than those described in this topic, use English (2924) as a primary language.
