可能是编码问题，中文默认系统编码是gbk，而你的json可能是utf-8。你可以尝试以gbk保存后再试。 It might be a problem with file encoding. The datamodel-codegen loads your json file with the system default encoding (GBK in simplified chinese env) and it failed. Try save it with GBK encoding and run the code-gen command again.

I had the same problem with my json files (and docs from mongo) - I dunno why but somewhere in the code yaml file reader is used and it throws errors when encouters specific unicode. Made a gist with script I use to clean json from those characters and generate pydantic class.
