Traditional Chinese is the official and most commonly employed writing system in Taiwan. Information systems of public agencies typically need to handle over 100,000 different characters.
Big5 is the first Chinese encoding that has been widely employed, followed by Unicode and the Chinese Standard Interchange Code CNS11643. Most agencies, however, are unable to adopt the newer CNS11643 because of technical and budgetary constraints. As a result, only a few public systems are capable of supporting CNS11643. This gives rise to issues such as loss of characters when exchanging information using different encoding systems such as Big5E, Big5, and Unicode 3.0. Problems include rare characters being replaced by black squares or user-created characters in official documents being replaced by error codes or blanks. Such incidents have proved detrimental to administrative processes as well as the rights and interests of the general public.
IISI assists the Department of Household Registration, Ministry of the Interior, to enhance their complex Chinese name database. IISI is experienced and more than capable of converting the current Big5 environment with 100,000 distinct Chinese characters into a system capable of supporting both CNS11643 and Unicode while safeguarding data integrity and consistency.
