If you, as a Uplay or Ubisoft Connect user, are encountering garbled emails or issues that you suspect are related to character encoding, here is a structured troubleshooting approach.

UTF-8 is the standard character encoding used across the internet to handle multiple languages and symbols. If this request fails, the client cannot verify your identity, resulting in login loops, connection timeouts, or initialization crashes. Common Causes

If the text looks garbled, view the raw source of the email (how to do this varies by email client). Look for the Content-Type header. It should contain charset="utf-8" . If it says iso-8859-1 , then the problem likely originates with Ubisoft's servers. If it says utf-8 , then the issue is with your email client failing to interpret it.

While most errors are standard ("Connection Lost" or "Password Incorrect"), one particular error message has become a cult classic of confusion:
