I got the same error when using non-english language, with english everything is perfect. Have you figured out the problem?

[Bryan Wilson (Appsembler)]

The Python string formatting code in lms/djangoapps/certificates/view/webview.py do not use unicode and will break when encountering non-ASCII text, for example, in a user's name or in a course name, or even the platform name.  I have fixed these errors for one of our customer's sites and am working on filing an issue/fix.  I'll repost here when I have done that.

Daniel and I just tracked down this issue. There were translations that should have had the placeholder {user_name} but instead had {username}. The error is because the code was trying to format the string, but there was no value provided for {username}. The KeyError is format's very unhelpful error message saying that it couldn't format the message because the placeholder with the given name was missing.

I've created a localization FAQ and described this problem and the solution here:
