Anaconda提示符启动失败：UnicodeEncodeError:“utf8”编解码器无法对字符“\udd8e”进行编码：不允许使用代理

Question

我有Windows 10 x64 en US和Anaconda3 2021.05。我的Python提示器正在工作。今天，它无法启动并显示错误：

# >>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<

    Traceback (most recent call last):

`$ C:\ProgramData\Anaconda3\Scripts\conda-script.py shell.cmd.exe activate C:\ProgramData\Anaconda3`

Anaconda PowerShell提示符也无法启动，出现类似错误：

# >>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<

    Traceback (most recent call last):
      File "C:\ProgramData\Anaconda3\lib\site-packages\conda\cli\main.py", line 140, in main

        print(activator.execute(), end='')
    UnicodeEncodeError: 'utf-8' codec can't encode character '\udd8e' in position 954: surrogates not allowed

`$ C:\ProgramData\Anaconda3\Scripts\conda-script.py shell.powershell activate C:\ProgramData\Anaconda3`

我四处搜索，尝试了一切，包括：

• 卸载并重新安装Anaconda
• 将Python升级至最新版本
• 将pythonionecoding=utf8添加到环境变量中
• 将“C:\ProgramData\Anaconda3”和“C:\ProgramData\Anaconda3\Scripts”添加到路径
• 正在删除tempfile.py

等等，无法修复它

我搜索了这个\udd8e字符：

This is an unassigned character within a valid range, meaning it could be designated a valid Unicode code point in the future. However, for now it has no assigned value.

我怎样才能解决这个问题？多谢各位
