写入文件时将 Python unicode 转换为 ASCII

我正在编写一个脚本来遍历音乐库并打印一个带有专辑名称日期......然后编号轨道的 .txt 文件。在导入的标签(如 unicode)变为 (-) 之前，它可以完美运行。然后我得到一个:

  File "C:/Users/Brian/Python files/CDinfoRF2.py", line 51, in music_album_info 
    mfile.write(header) 
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in position 18: ordinal not in range(128). 

代码:

#!usr/bin/env python 
__author__ = 'Brian Kane' 
 
"""This scripts takes a path argument to the root directory of the music files (mp3 here) and 
   writes various information about the disc to a text file which is named by the artist"""

    mfile.close() 
 
path = 'C:\\test'                       # this is a test path 
# path = raw_input('Enter the path to the music file:\n>') 
 
music_album_info(path) 

请您参考如下方法:

您丢弃了专辑的 UTF-8 编码:

album.encode('utf-8') 

字符串是不可变的；您基本上丢弃了 bytestring 返回值。存储它:

album = album.encode('utf-8') 

您可以改为使用 io.open() function打开一个文件对象，自动将所有写入它的 Unicode 编码为 UTF-8:

with io.open(file_name, 'a', encoding='utf-8') as mfile: 
    mfile.write(header) 

在这种情况下，您根本不需要对 album 进行编码。
