编码IssuePython

Question

我正在写一个程序来读取一首歌的mysql表，然后在youtube上找到这首歌。我想下载这首歌并把它放到我的soundcloud帐户上。我试过为此编写代码。问题是每次运行它时，都会遇到以下问题：

Non-ASCII character '\xe2' in file on line 164, but no encoding declared

请帮助解决同样的问题。你知道吗

您在此处使用了错误的引号： 换行164

相册_艺术编码（'utf-8'），>；相册_艺术编码（'utf-8'）

如果使用十六进制编辑器，可以搜索char 0xe2并用0x27替换它们。你知道吗
