The rapid growth of the occasions of both international and national communications among people from various countries urge the computer environments nowadays to ensure the unambiguous interchange or processing of necessary informations. Most current approaches, however, especially the one with the Locale model, are apparently going backward, so impeding the sound development of a computer in terms of its computability and interoperability. Suppose you mix unlimitedly all character sets on a computer, which means its Multilingual environment[1]. Mb is motivated as a unit for information exchange, as defined in ISO 2022[2], but its codepoint does not necessarily correspond to one character, because of its extension with the control sequences and the code extension techniques defined in ISO 2022/6429 [3] and with determinatives [5]. Nor is WC a unit to process as a character,although POSIX, X Intrinsics and X Widgets assume so. Posix defines WC as an implementation dependent internal code, so it is not appropriate for codeset independentmultilingual text manipulation.In the following sections, the concept of TMC (Text Manipulation Code) and the informations necessary for proper text manipulation are presented, a generalization of text manipulation.
