9    Input Methods

This chapter describes the differences in input methods between Tru64 UNIX and HP-UX. Both Tru64 UNIX and HP-UX provide input methods for Japanese, Korean, Simplified Chinese, and Traditional Chinese. Tru64 UNIX also provides a multilingual input method.

9.1    Japanese Input Methods

Tru64 UNIX provides the dxjim input method to input Japanese characters. HP-UX provides the xjim and ATOK X input methods. The differences between the input methods are as follows:

• Input functionalities

  All the Japanese input methods provide a kana-kanji conversion Japanese input functionality, which is commonly used in Japan. The dxjim method uses the JSY library as the kana-kanji conversion engine, while xjim uses Kana Kanji conversion server (kks).

• Preedit types

  The X Window System defines four preedit types for input methods: on-the-spot, over-the-spot, off-the-spot, and root. Table 9-1 shows the preedit types supported by the Japanese input methods.

  Table 9-1:  Preedit Types for the Japanese Input Method

  Preedit Type	dxjim	xjim	ATOK X
  on-the-spot	Yes	No	Yes
  over-the-spot	Yes [Footnote 23]	Yes [Footnote 23]	Yes [Footnote 23]
  off-the-spot	Yes	Yes	Yes
  root	Yes	Yes	Yes

• Start key and End key

  A Start key is a key on the keyboard that activates the input method for the focused window application. An End key is a key that deactivates the input method for the focused application. Table 9-2 shows the default Start key and End key for the Japanese input methods.

9.2    Korean Input Methods

Tru64 UNIX provides the dxhangulim input method to input Korean characters. HP-UX provides the xkim input method. The differences between the input methods are as follows:

9.3    Simplified Chinese Input Methods

Tru64 UNIX provides the dxhanziim input method to input Simplified Chinese characters. HP-UX provides the xsim input method. The differences between the input methods are as follows:

• Input functionalities

  Table 9-6 shows the input functionalities provided by the Simplified Chinese input methods.

9.4    Traditional Chinese Input Methods

Tru64 UNIX provides the dxhanyuim input method to input Traditional Chinese characters. HP-UX provides the xtim input method. The differences between the input methods are as follows:

• Input functionalities

  Table 9-9 shows the input functionalities provided by the Traditional Chinese input methods.

9.5    Multilingual Input Methods

Tru64 UNIX Version 5.1B provides a multilingual input method called dxim. Currently, dxim supports Korean, Simplified Chinese, and Traditional Chinese input functionalities provided by dxhangulim, dxhanziim, and dxhanyuim. HP-UX does not provide a multilingual input method.

9.6    Selecting an Input Method

In Japanese locales on HP-UX, a small window appears at the start of CDE session that contains a list of Japanese input methods provided by the system. You can choose one input method (or nothing) for that session. This is done by the CDE 2.1 standard dtimsstart command. Tru64 UNIX provides dtimsstart, too, but it is the CDE 1.0 version and different from the HP-UX version. Tru64 UNIX does not provide such input method selection functionality.
