哥巴文是一种音节文字,它的经书数量很少且分布地域较窄。我们通过编制《大祭风·超度董族的吊死者·卷首》这本纯哥巴文经典的字表,进行了个案字符体系的研究,同时也初步探讨了这本经书中异体字和同形字的特点。通过研究可以看出哥巴文还是一种处于初级阶段的音字,它是在表词文字东巴文的基础上由于客观的需求而演变出来的。它的同形字和异体字很多,但也已经开始走上规范的道路。 Kuba is a syllabic text, with a small number of scriptures and a narrow geographical distribution. We made a case study of the character system through the compilation of the pure script of the classic scriptures of “God, Death and Death” of " . It can be seen from the study that Kuba is still an initial sounding word evolved from objective needs based on the Dongba script. It’s a lot of homographs and variant characters, but it has also begun to take the standard path.
