Abstract

Main point of this invention Disclosed is a Japanese input method which restricts the code range of input characters to JIS X 0208 (1st level and 2nd level), 3rd level, or 4th level, when inputting JIS X0213 characters. It also displays variant characters as input candidates with the information about the code range at the time of a code input. Problems solved by the invention The code range of input characters is expanded by support of JIS X 0213. However, there is a case when the code range of input characters should be restricted, because a problem may happen in data compatibility with the system which is not supporting JIS X 0213.

Input method with restriction of the input code range

Main point of this invention

Disclosed is a Japanese input method which restricts the code range of input characters to JIS X 0208 (1st level and 2nd level), 3rd level, or 4th level, when inputting JIS X0213 characters. It also displays variant characters as input candidates with the information about the code range at the time of a code input.

Problems solved by the invention

The code range of input characters is expanded by support of JIS X 0213. However, there is a case when the code range of input characters should be restricted, because a problem may happen in data compatibility with the system which is not supporting JIS X 0213.

How does the invention solve problems?

The following functions are added to the input method for JIS X 0213.
1. An input mode is provided to restrict the code range of input character to one of JIS X 0208 (1st level and 2nd level), 3rd level, or 4th level.
2. The code range information can be displayed, even when characters of the code range of the 3rd and 4th level (JIS X 0213) can be inputted.
3. If possible, variant characters are also displayed as candidates with the information about the code range, when the variant characters are not outside of the code range.

Composition of the invention

1. The input method allows following two specifications to be set.
(1) The code range of inputable characters

a. 1st and 2nd level (JIS X 0208)

b. 1st, 2nd and 3rd level (JIS X 0208 + 3rd level of JIS X 0213)

c. 1st, 2nd, 3rd and 4th level (JIS X 0213)
(2) Displaying the information about the code range

Displaying the level information or not, if the inputting character is 3rd or 4th level.

The input method checks the code range of the inputting character according to the setting of above (1). The converted candidate word is not displayed if it includes a character which is outside...
