ABSTRACT:
The present invention is a method and apparatus for translating an input character from a source codeset to a target codeset. Structurally, the present invention includes a list of translation tables each having one or more entries. Each entry in a translation table defines a translation from a character in the source codeset to a character in the target codeset. Each translation table also includes an entry condition function and an input normalization function. To translate an input character in the source codeset to the target codeset, the list of translation tables is traversed until an entry condition is found which returns a boolean value of true when called with the input character is passed as a parameter. Then input character is then passed to the input normalization function which returns the index or position of the translation for the input character in the translation table. The contents of the translation table, at the index, is then returned as the translation of the input character.
