Abstract

A code conversion system that takes direction into consideration when converting characters from a source character encoding to a target character encoding is disclosed. The code conversion system is able to map a single source character or a sequence of characters to either a single target character or a sequence of target characters. By determining or resolving the direction of the characters being converted, the code conversion system can then utilize the determined or resolved direction of the characters to ensure that the correct mapping to the target character encoding is obtained.
