Abstract: In order to reduce the data storage of font library, on the basis of using deterministic finite automata to establish the glyph mapping relationships of square Hmong characters obtained by component transformations, a development method of the square-Hmong-characters font library, which supports component reuse, is proposed. The concrete development process of the square-Hmong-characters font library based on this method is given. According to the glyph mapping relationships, the proposed method uses the OpenType feature tags to design feature scripts, which reflect the substitution rules and positioning rules for free combination of components, so as to realize the reuse of same component glyph in different square Hmong characters. The test result shows that the font library developed by the proposed method has the advantages of small storage capacity, easy expansion and so on, and can realize the mixed display of the Hmong, Chinese and English, and can meet practical requirements.
