-Python-解码/读取文件的问题

Question

我想使用一个名为“ Noesis”的程序从.m3d文件中加载模型。从另一个论坛（我对python不太满意），我获得了脚本片段作为Noesis的插件，应将其导入模型。问题是，我得到以下错误：

 C:\Users\Username\Documents\NOESIS\plugins\python\fmt_swl_m3d.py
", line 42, in m3dLoadModel

nodeName=bs.readBytes(nodeNameSize).decode("ASCII")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd2 in position 2:

ordinal not in range(128)

显然，它与解码部分有关，但是如果我将其更改为“ latin-1”，“ utf-8”或将其保留为空，它仍然会给出相同的错误或类似的内容：

Error message

由于使用了程序和库，我不希望有任何具体的帮助，但是有关如何解决此问题的任何建议都会有很大帮助。我花了很多时间解决这个问题...

提前感谢！

我也有一个python错误，仅使用.bndl文件提取器，并且使用该格式的3D模型
