Encoding problem when trying to translate srt file from EN -> CN；英文字幕文件翻译中文时编码问题

[Kaiyiccc]

Describe the bug

使用音频直接生成英文字幕正常。试着翻译生成的英文 srt 文件，出现以下报错： When trying to translate an srt file, I get the following error:

AttributeError: 'NoneType' object has no attribute 'encode'

To Reproduce Steps to reproduce the behavior:

Ky-iMac:autosub home$ source test1/bin/activate
(test1) Ky-iMac:autosub home$ autosub -i /Users/home/autosub/test1/bin/output.srt -D zh-CN

• A complete copy of command line output of the autosub. You can use Ctrl-A and Ctrl-C to copy all of them.

No output format specified. Use input format "srt" for output.
Input is a subtitles file.

    return value.encode(encoding or "ascii")
AttributeError: 'NoneType' object has no attribute 'encode'

Expected behavior

我也试着更改环境默认的 LANG 和 LC_ALL 至 en_US.UTF-8。但这似乎不是问题所在 I also tried setting the LANG and LC_ALL to en_US.UTF-8.

Environment (please complete the following information):

• OS: MacOS High Sierra 10.13.6
• Python Version: 3.8.6
• Autosub Version: autosub 0.5.7-alpha by Bing Ling binglinggroup@outlook.com

Additional context 坐标北美，应该没有网络问题 I am located in the US so internet access shouldn't be a problem.
