文章选取了一部分笔写本的日本金刚寺本《玄应音义》的非正字,将它们与《初雕本高丽大藏经》和敦煌写本进行比较,揭示出它们是误字还是异体字。研究结果如下:倘若字形反复使用,致使约定俗成,或者由于各种理由,存在故意写成其他字形的可能性,也可视为异体字。反之,仅仅是单纯地写成了截然不同的字形,应将其视为误字。 The article selects a part of the non-orthographic texts of the “Jingyin Yinyi” of King Kong Temple in Japan and compares them with the “Buddhist Scriptures of the Early Buddhist Scriptures of Korea” and Dunhuang Manuscripts to reveal whether they are typo or variant characters. The findings are as follows: If glyphs are repeatedly used, resulting in conventions, or for various reasons, there is the possibility of intentionally writing other glyphs, they can also be regarded as different characters. Conversely, simply writing a completely different glyph should be treated as a typo.
