Failed to load page error when editing inplace a terminal page with a question mark in the name

Steps to reproduce:

• create a terminal page with a question mark in the name
  • if naming strategy is activated to cleanup special characters from the names, make sure you disable it to really have the question mark in the page name, not only in the title
• fill in some content in the editor
• save and view
• click the edit button in view mode, to activate inplace edit

Expected result:

• the page is loaded in edit mode

Actual result:

• the edit mode is not activated on the page

In the browser dev tools in network tab, a request with a 404 is loaded , with a rest URL in which the ? character from the name of the page is escaped.
