Abstract
Abstract A method and apparatus for providing a translation environment for a computer system. Structurally, the present invention includes three main components: a codeset manager, a codeset database, and a codeset translation engine. The codeset manager compiles a set of codeset definitions. The compiled codeset definitions, or translation methods, are included in a codeset database. To translate a character, a client process requests the translation, specifying a source codeset and a target codeset from the codeset translation engine. The codeset translation engine transmits the requested translation to the codeset manager which searches the codeset database for an appropriate translation method. If no appropriate translation method exists in the codeset database, the codeset manager may be able to create a translation method using one or more translation methods in the codeset database. If an appropriate translation method is found or created, the translation method is executed to perform the requested translation. The translated character or characters are then returned to the client process.
