In this paper, we propose a character processing system (undefined character processing system) that handles characters for which fonts or character code systems have not been provided on the terminals (undefined characters). The undefined characters include characters historically not installed in the input/output environment, such as ancient characters or characters used by minority groups, and characters not used in a particular language system environment. The proposed system uses morphology to analyze the structures of the target undefined characters, generates codes which describe the characters' shapes based on the analysis results, and reconstructs the characters from these codes. A prototype of this system was constructed. The results of the structural analysis of the undefined characters and their reconstructions verified the effectiveness of the proposed system. © 2000 Scripta Technica, Syst Comp Jpn, 31(9): 60–71, 2000
