Python源“编码未声明”

这是我的源文件的顶部：Python源“编码未声明”

# -*- coding: UTF-16 -*- 
import re 
import unittest

尽管包括在文件的顶部声明，当我运行此我得到一个错误：“非ASCII在第1行的文件ScrapeEdgar/parsers/parser8kex101_tests.py中有字符'\ xff'，但没有声明编码;详情请参阅http://www.python.org/peps/pep-0263.html“。

下面是完整的输出：

你有没有试过'#coding = utf-8'？ –

Python源文件不支持UTF-16编码。

任何编码，它允许处理在上面指出的被允许作为源代码编码方式的前两行，这包括ASCII兼容编码以及某些多字节编码如SHIFT_JIS。它不包括编码，对所有字符使用两个或多个字节，例如 UTF-16。其原因是保持标记器中的编码检测算法简单。

请参阅PEP 0263。

希望这会有所帮助。
