发送推文时，Crontab有unicode错误-Crontabhasunicodeerrorwhensendingtweet

I am currently running a python script to detect changes in a website's json object that consists of products.

我目前正在运行一个python脚本来检测由产品组成的网站json对象的变化。

When i run it manually on my ubuntu server it works fine (sends tweet) but when it is run with the crontab, it gives me this error:

当我在我的ubuntu服务器上手动运行它工作正常（发送推文），但当它与crontab一起运行时，它给了我这个错误：

UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 20: ordinal not in range(128)

UnicodeEncodeError：'ascii'编解码器无法对位置20中的字符u'\ xa0'进行编码：序数不在范围内（128）

Here is the code. Basically I am comparing different versions of the json file to see if there's a difference. If there's a difference, send a tweet.

这是代码。基本上我正在比较不同版本的json文件，看看是否有区别。如果有区别，请发送推文。
