Databases supporting Hangul (or Korean script)

A major obstacle to building databases supporting both modern and ancient Hangul is that not all ancient complex characters are known yet. It is shown that a very flexible code, keyboard, and output method can be developed to overcome this obstacle. The author proposes an ancient-Hangul code that can be added to ISO 8859, a three-set ancient-Hangul keyboard, and an output method. Because the framework of the current Korean government standard modern-Hangul code and keyboard do not allow the development of an efficient ancient-Hangul code and keyboard, the author suggests that the government abandon the current framework and adopt the development of the suggested framework
