They specify only small code regions of private characters. Thus existing standards do not promote global digital libraries which need to use non-standardized symbols. In most multilingual information processing systems, implementations are strongly affected by their own concepts of glyphs, characters, scripts and languages. Therefore existing systems usually permit only their own canonical concepts, and force users to obey the concepts. The author does not think that this type of enforcement facilitates present day multi-cultural information processing.
Separation of concerns is important in information processing systems.
Multilingual information processing systems should permit various ideas, concepts and policies to coexist, and process various data efficiently using smart mechanisms. It is capable of handling general symbols as well as currently used characters, and it is also customizable. In this paper, symbols can include not only characters but also glyphs, marks, signs, logos, tags and even sound elements. Customization and standardization are not antithetical concepts but are complementary to each other. The process of standardization will not terminate in our evolving world.
