Abstract

A list display apparatus that displays multiple pieces of character string data in a list on a display unit includes a storage unit that stores the multiple pieces of character string data; a sorting unit that sorts the multiple pieces of character string data stored in the storage unit in a character code order; a ligature decomposing unit that decomposes a ligature included in the multiple pieces of character string data into multiple original letters on which the ligature is based in the sorting by the sorting unit; and a sorting control unit that controls the sorting unit so that the multiple letters resulting from the decomposition by the ligature decomposing unit is used in the sorting, instead of the ligature.

First claim

What is claimed is:

1. A list display apparatus that displays multiple pieces of character string data in a list on a display unit, the list display apparatus comprising:
a storage unit configured to store the multiple pieces of character string data;
a sorting unit configured to sort the multiple pieces of character string data stored in the storage unit in a character code order;
a ligature decomposing unit configured to decompose a ligature included in the multiple pieces of character string data into multiple original letters on which the ligature is based in the sorting by the sorting unit;
a replacement unit configured to replace a part of the ligature in each piece of character string data including the ligature with only a first letter of the multiple letters resulting from the decomposition; and
a sorting control unit configured to control the sorting unit so that the pieces of character string data after the replacement by the replacement unit are used in the sorting, instead of the pieces of character string data including the ligature,
wherein the multiple pieces of character string data are displayed in the list according to an order of the sorting by the sorting unit under the control of the sorting control unit.

2. The list display apparatus according to claim 1 ,
wherein the pieces of character string data including the ligature are displayed in the list in a display mode in which the ligature is included.

3. The list display apparatus according to claim 1 ,
wherein the multiple pieces of character string data include data read from an external device.

4. The list display apparatus according to claim 1 ,
wherein the multiple pieces of character string data include data searched for from a database under a certain search condition.

5. The list display apparatus according to claim 1 ,
wherein the multiple pieces of character string data include pieces of character string data in Arabic.

6. The list display apparatus according to claim 5 ,
wherein the ligature decomposing unit decomposes a ligature in Arabic letters into multiple original letters regardless of whether the ligature in Arabic letters is used in an independent form or as a last letter.

7. The list display apparatus according to claim 5 ,
wherein the ligature decomposing unit decomposes the ligature on the basis of a table in which a correspondence between the ligature and the multiple original letters is described.

8. A list display method that displays multiple pieces of character string data in a list on a display unit, the list display method comprising:
a first step of detecting a ligature from the multiple pieces of character string data stored in a storage unit;
a second step of decomposing the ligature detected in the first step into multiple original letters on which the ligature is based;
a third step of replacing a part of the ligature in each piece of character string data including the ligature with all of the multiple letters resulting from the decomposition or only a first letter of the multiple letters resulting from the decomposition;
a fourth step of sorting the multiple pieces of character string data in a character code order, wherein the pieces of character string data after the replacement in the third step are used in the sorting instead of the pieces of character string data including the ligature; and
a fifth step of displaying the multiple pieces of character string data in the list according to an order of the sorting in the fourth step.

9. The list display method according to claim 8 ,
wherein the third step includes
determining whether the part of the ligature is replaced with all of the multiple letters or only the first letter of the multiple letters depending on a type of the list to be displayed, to which the pieces of character string data including the ligature belong; and
performing the replacement in accordance with a result of the determination.

10. The list display method according to claim 8 ,
wherein the fifth step displays the pieces of character string data including the ligature in the list in a display mode in which the ligature is included.
