Abstract:

To effectively solve the glyph generation and glyph description problem, a dynamical glyph generation method of Xiangxi folk Hmong characters is proposed. According to this method, the glyph generation process can be described as a combination arithmetic expression. Hmong characters component acts as the operand, and the location relationship between the components decides the operator. Glyphs in different structure can be dynamically generated by combination of two or three components. Further, if combination arithmetic expression is converted to ideographic description sequence (IDS), the proposed method can be implemented with the help of the IDS explain mechanism of operation system. Test results illustrate that, the Xiangxi Hmong characters glyph, which generated by the mapping script based on the proposed method, can meet practical requirements.

Key words: Folk Hmong characters, glyph, context-free grammar, ideographic description sequence (IDS)

摘要：

为了有效地解决湘西民间苗文字形的生成及描述问题, 提出一种字形的动态生成方法。该方法将苗文字形的生成过程表示为由苗文构件作为操作数、由构件位置关系决定运算符的组合运算表达式, 将2~3个构件进行不同的组合运算, 即可动态生成不同结构的苗文字形。利用操作系统自带的表意文字描述序列解释机制, 将构件组合运算表达式转换为表意文字描述序列, 即可实现该方法。测试结果表明, 根据该方法编写的映射脚本生成的湘西民间苗文字形可以满足实用要求。
