python-2.7 - 在 Jython 中提取 zip 文件时，“TypeError：字符映射必须返回整数、无或 unicode”

问题描述

假设和我想要实现的目标

我正在使用Python2.7 (Jython)编写代码，因为我使用的是 ImageJ。

我想在 Python 2.7 中提取 zip 文件，但我做不到。

我在文件夹“OutletHDD”中有一个名为 RoiSet.zip 的 zip 文件，我想将其解压缩到文件夹“hoge”中。

遇到的问题和错误信息

源代码。

import zipfile
from ij.plugin.frame import RoiManager
from ij.process import ImageProcessor
zippath = "C:\Users\For Programming\Documents\Python Scripts\OutletHDD\RoiSet.zip"


ZipObj = zipfile.ZipFile(zippath) 
ZipObj.extractall("C:\Users\For Programming\Documents\Python Scripts\OutletHDD\hoge") #Unzip and move the Zip file
ZipObj.close()

我试过的

我以为可能是unicode类型、str类型的bug，我想尝试做str()、unicode()等，但是没有成功。

附加信息（固件/工具版本等）

我从日本写代码（可能与字符代码有关）

Windows10 64位

我想了解这方面的任何信息，如果我的信息不足，请告诉我
