Unicodedecodeerror：＆＃x27; Charmap＆＃x27;编解码器可以在位置2501中解码字节0x81：字符映射到＆lt; undefined＆gt;

Question

我一直在寻找解决方案，但还没有找到任何有效的方法。我尝试在filepath的前面添加R。我尝试将编码更改为UTF-8。似乎没有任何作用。

我在Mac上写了此脚本，它运行良好，并且正在尝试在Windows上运行它，但它不起作用。

fin = open("C:\\Users\\filepath\\indivsWG22.txt", "rt", encoding = 'ISO-8859-1')
fout = open("C:\\Users\\filepath\\Downloads\\out.csv", "w")
#for each line in the input file
for line in fin:
    #read replace the string and write to output file
    #This is where I deal with all the pipes and commas
    fout.write(line.replace(',', '^').replace('|~|',',').replace('|~',',').replace('~|',','))
#close input and output files
fin.close()
fout.close()

这是我遇到的完整错误：
