• International networkings with a lot of intennational/national code sets spread as common environment of daily use. And users of different nationalities have shared one computer on such environment Thus, it is essential to process and to communicate texts in multiple code sets simultaneously and consistently. On the other hand, current approaches to Internationalization (I18N) are mainly adapting a system to one specific language based on POSIX Locale Model, which is only a localization to a bi-lingual system. Since POSIX does not inhibit to define multi-code-set (MCS) Locale, it is possible to set MCS Locale, But the Locale reveals contradictions of the Locale model. To be an I18N system, four components, I/O, Text Manipulation/Communication (TM/C) are essential, and all components must ensure computability and interoperability in unlimited use of set of MCS. Then all the functions work consistently by defining each element of MCS after extensions (in Perso Arabic scripts, Final Glyph Set to be displayed is larger than its Graphic Character Set. As a trial in a part of I18N, X11R5 OM (Output Method) and IM (Input Method) were designed and implemented. In R5, a set of limited MCS was provided. But in R6, its OM and IM are hard-coded to a locale. R5 and R6 do not ensure computability, and are not I18N system by the limitation from the Locale model. Also ICCCM does not ensure interoperability that occurs from code set design. Thus, new I1SN model that satisfies MCS Locales (Multi local Model) was established by our researches based on world's writing scripts and code sets. And for satisfying TM/C and essential factors out of ISO specifications - beyond the new I18N model - more general model (Global IOTMC Model) covering the four components was established and the Multilingual and TM/C System was newly developed.
