Summary

Some non-ASCII Unicode characters break the "Answer this question" link in notifications generated by Confluence Questions.

Environment

• Confluence 6.2.1
• Confluence 7.3.1
• Up to Questions for Confluence 2.7.21.

Steps to Reproduce

1. Create a new Question with the title, "Test ąćęłńóśźż".  In this example the characters are Polish.
2. Open the email notification generated afterwards, and click on "Answer this question".

Expected Results

You are able to open the link and answer the Question within Confluence.

Actual Results

Instead, the browser throws an error such as the below:

// HTTP Status 401 - Expecting claim 'qsh' to have value '81b5e16f336512f1069a85f0697794052fa83f2f96dc5518ec284f3e24ce1660' but instead it has the value '68bb7e0b17e5f9ff332c8d35a3f321f15ddc79d27278148435a6d6b33e28c6b8'

Workaround

Remove the characters from the title, best bet is to use ASCII characters.
