对非通用语言文字进行立法，既是规范和保护、促进非通用语言文字发展的现实之需，也是坚持依宪治国、依宪执政的必然要求。非通用语言文字立法，应关切实质民主原则下的少数群体和弱势群体的语言权利，确保推广普及通用语言文字与语言多样性的均衡。鉴于此，本书专门研究除国家通用语言文字外的非通用语言文字立法问题。本书首先论述非通用语言文字立法理论基础与现实基础，然后以各论的形式分别论述了汉语方言、少数民族语言文字、手语盲文、网络语言文字、繁体字与异体字以及外来语的立法理论与实践问题。

Legislating non-lingua franca is not only a practical need to standardize, protect and promote the development of non-lingua franca, but also an inevitable requirement for adhering to governing the country and governing according to the constitution. Legislation in non-lingua franca should take into account the linguistic rights of minorities and vulnerable groups under the principle of substantive democracy, and ensure the promotion of universal access to a common spoken and written language and a balance between linguistic diversity. In view of this, this book is devoted to the study of the legislation of non-standard spoken and written languages other than the standard spoken and written languages of the country. This book first discusses the theoretical and practical foundations of legislation in non-common languages, and then discusses the legislative theory and practice of Chinese dialects, minority languages, sign language Braille, Internet languages, traditional and variant characters, and foreign languages in the form of monographs.（AI翻译）
