SyntaxError: Non-ASCII character but no encoding declared [duplicate]

Question

I am suppose to change some of these characters in English to Chinese in this setting.py file but then error happened.

I know that it's saying because no encoding is declared in the error message but I have been reading a few posts and still have no idea how / where I can make it happen.

in my setting.py I have something like this

OSCAR_DASHBOARD_NAVIGATION = [
{
    'label': _('dashboard'),
    'icon': 'icon-th-list',
    'url_name': 'dashboard:index',
},

but need to change the navigation to Chinese so ended up looking like this

OSCAR_DASHBOARD_NAVIGATION = [
{
    'label': _('仪表板'),
    'icon': 'icon-th-list',
    'url_name': 'dashboard:index',
},

Edit, I already read the post which thought might be duplicated and tried what's in that post and instead of getting errors, I get a no show in my page but regarding to Pedru's answer. It works like a charm now.

Answer 1

Try adding

# -*- coding: utf-8 -*-

at the beginning of the file, make sure your file is really encoded in utf-8
