Some unicode characters are not properly encoded on OpenURL submissions if the user must log in first.
This seems to be a new issues introduced in ILLiad 8.7 when we switched to Delphi XE 8. To reproduce, submit an OpenURL request using the included URL both with and without a session. When you're already logged in, the cyrillic characters are rendered correctly in the author field and a ligature is used in the title. If you don't have an active session and are sent through the logon2 page, those fields will be rendered as ?s or boxes, indicating a problem with the form state encoding. I confirmed this URL worked correctly on ILLiad 8.6.x and earlier.2 votes
