Problems solved by technology

However, most of its solutions are aimed at database conversion technology, and there is no effective method for characters that are not composed of letters and numbers, such as Chinese, Japanese or Korean, etc.

Embodiment Construction

[0026] Please refer to figure 1 , figure 1 It is a schematic diagram showing the source character set, intermediate character set and target character set disclosed in the present invention. As shown in the figure, according to the US7ASCII character set, Chinese characters 10 "李", 12 "柏" and 14 "Tong" will be encoded as (a7, f5), (ac, 66) and (ae, e4).

[0027] The WIN950 character set is selected as the intermediary character set, because the character codes of Chinese characters encoded by the WIN950 character set are the same as those of the US7ASCII compatible character set. At the same time, the UTF-8 character set is the complete parent set of the WIN950 character set, so the character encoding can be directly mapped to the UTF-8 character set from the WIN950 character set.

[0028] Then, the first conversion is performed to convert the encoding of the characters from the US7ASCII character set to the WIN950 character set. The first conversion first records the char...

Abstract

The present invention provides a computer-implementable character set conversion method and system. The computer-implementable character set conversion method is used to convert character codes from a source character set to a target character set, and the target character set is not the source character set. The complete parent set of . First, characters to be converted are provided, and each character can be encoded into a first character code according to the source character set. Next, select an intermediary character set. The intermediary character set can make the character code of each character the same as the first character code encoded by the source character set, and the target character set is a complete parent set of the intermediary character set. Then, a first conversion is performed to convert the encoding of the characters from the source character set to the intermediate character set. Finally, a second conversion is performed to convert the encoding of the characters from the intermediate character set to the target character set, and each character can be encoded into a second character code according to the target character set. The invention can be applied to databases encoded with different character sets to solve the problem of character conversion.

Description

technical field [0001] The present invention relates to a character conversion technology, in particular to a method and system for converting a coded character set. Background technique [0002] In data processing, data may be distributed in different storage devices or different operating devices, such as different databases or computer systems. Therefore, many data-related processing operations, such as data selection (selection), data deletion (deletion) or data integration (integration), etc., are interactively performed in different databases or computer systems. However, each database usually has its own character set for encoding the characters stored therein. [0003] When different databases use the same character set for character encoding, data can be directly processed and manipulated in different databases. Alternatively, although the databases use different character sets, if the character codes after encoding the characters are the same character code, the ...
