A system providing improved National Language Support (NLS) in application programs is described. The system employs normalized Unicode data with generic transformation structures having locale overlays. Methods are described for navigating the structures during system operation, for effecting various transformation processes using locale-specific information. The locale-specific information is maintained in the structures as external data files. Since the data files are read in at runtime, the underlying binary files which comprise the program need not be modified for updating the program to support a new locale. The approach provides extensibility to applications with National Language Support. Additionally, increased portability is provided, since manipulation of the underlying data remains unchanged regardless of the underlying platform. Program maintenance is also decreased, since engineers need only maintain a single core.
