windows上python3默认encoding是gbk出错，open()需要加encoding

[sieveLau]

报错是这样：

> python hugo-encryptor.py   || exit
Traceback (most recent call last):
  File "hugo-encryptor.py", line 133, in <module>
    f.write(str(soup))
UnicodeEncodeError: 'gbk' codec can't encode character '\xa9' in position 2259: illegal multibyte sequence

查了一下，在hugo-encryptor.py的131行的with open(fullpath, 'w') as f:里面加encoding="utf-8"，变成：

            with open(fullpath, 'w',encoding="utf-8") as f:
            html = str(soup)
            f.write(str(soup))

以及166行的open也同样加一个encoding，就不报错了。
