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 ...
