The Multilingual text Processing(5) : Extension of POSIX to Multilingual Processing

概要

論文の詳細を見る
Most Systems have been constructed based on POSIX Locale Model or limited multilingual models, which do not full support ISO 2022. Especially, the system based on POSIX Locale Model dos not work correctly at interactive locale selection due to the ambigous POSIX specifications which do not have farther interpretations.To process simultaneously all scripts in the world, Global IOTMC Model was established by the analyses of Charater,Codest and Text Processing in the world, which supports ISO 2022 and other code extensions beyond ISO specifications. Since a system internal code (WC) was normalized to one Charater and includes not only an identifier but also the drawing infromation, etc., WC is converted uniquely without locale dependencies. As a result, all of the codesets can be processed simultaneously. And, the relation between this model and POSIX Locale Model was defined clearly for keeping backward compatibilities. The system 1, developed based on Global IOTMC Model by Waseda University, provides the informationalized computing environment.
