Hi,

UnicodeDecodeErrors are quite common in Python 2, when you add an UTF8 character and the system is not set up for it (usually, you need to start your code with `# encoding: utf-8`).

But the fact that this seems to affect socket is weird as heck. I'd check anything in mytestsite/settings.py to make sure there isn't an UTF8 string in anything related to server name (things like DATABASE, in which you define the host for your database and the like).

Hi,

I took a longer look at the error and it seems the error raised when the server was starting up. The code tries to figure out your machine name -- a thing that's stored, on Linux systems, on /etc/hostname and on OS X on Settings -> Sharing -- and *that* name has special characters (I'd guess it could be something like "曹逍遙's computer").

I don't have enough knowledge about Windows to know where you could change that.

Hello Julio Biason

I just changed my host name

That's right, it's really a question of the host name.

Now normal startup~~

Thank you very much  Thank you very much

👍
