Question

我想将图像从reddit保存到本地文件：

import urllib.request
urllib.request.urlretrieve(post.url, "local-filename.jpg")

要进行复制，只需将post.url替换为包含“ä”的URL

但是有一天我偶然发现了一个错误：reddit帖子网址的标题中带有“ä”。

我知道这与一个基本的Python unicode问题有关，并且我读了UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 20: ordinal not in range(128)，但是我不知道如何将修复程序应用于我的问题。

这是我得到的错误：

如果URL中有特殊字符（“ä”），为什么urllib.request.urlretrieve失败？
