UnicodeDecodeError：“ascii”编解码器无法解码位置 0 的字节 0xef：序数不在范围内（128）

Question

我的主题有 .js 文件，它曾经可以工作。但是今天当我注释掉一些代码行，或者只是打开并保存并更新我的应用程序时，我得到了这个错误

UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128)

完整的错误是

我的档案是https://dl.dropboxusercontent.com/u/27576887/StackOverFlow/charisma.js 我在 VS 2012 中打开并编辑文件 请告诉我这里有什么问题？ 谢谢！

Answer 1

文件保存为没有签名的 Unicode UTF-8。 我把它改成了日文的 SHIft-JIS，它又能用了。

Answer 2

显然这是一个编码问题：您的代码中有一个或多个字符在上传时无法解码。 Check sendBatch method at 1282

如果您可以不使用有问题的字符，那么您就可以开始了。 Otherwise, it seems that updating your server directly through appcfg.py in terminal makes it.

python appcfg.py update

不管怎样，追踪这个问题的进展会很有趣。
