In this paper, we designed and implemented a code conversion method between ISO/IEC 10646 and the multi-byte code set. The Universal Multiple-Octet Coded Character Set(UCS) provides codes for more than 65,000 characters, huge increase over ASCII's code capacity of 128 characters. It is applicable to the representation, transmission, interchange, processing, storage, input and presentation of the written form of the language throughout the world. Therefore, it is so important to guide on code conversion methods to their customers during customer systems are migrated to the environment which the UCS code system is used and/or the current code systems, i.e., ASCII PC code and EBCDIC host code, are used with the UCS together. Code conversion utility including the mapping table between the UCS and IBM new host code is shown for the purpose of the explanation of code conversion algorithm and its implementation in the system. The programs are successfully executed in the real system environments and so can be delivered to the customer during its migration stage from the UCS to the current IBM code system and vice versa.

UCS (=ISO/IEC 10646, =Unicode) will be used widely as globalization. If UCS is used for official purpose in Koreas, UCS solves a Problem in different hangeul code between South and North Korea. But, UCS is not a solution for problems in unequal order with the same character. IS0/1EC 146sl : 2000 (International String Ordering), which is a international standard for string ordering, defines a framework sorting all char-acter strings consisting multi-national scripts. Because the Common Template Table in ISO/IEC 14651 defines orders of characters, we can change orders of characters without changes of characters sequences in programs. Therefore, we can solve a ordering problem without unifying order of hangeul in South and North Korea. Functions related ISO/IEC 14651 are contained by system librarys in unix-based operating system such as Linux, Solaris and FreeBSD. We implement EUC-KR-based North Korean locale, which includes North Korean hangeul order, in Linux in order to use North Korean locale in South Korea. And we develop a program ordering strings with South and North Korean hangout order.
