Autoconvert doesn't deal with %7C on internal URLs correctly

The Autoconvert Confluence module of Confluence Paste plugin is not dealing with %7C on internal URLs correctly. If I paste following URL on a personal space page:
"https://confluence.example.com/display/CO/GD-0147+%7C+My+Page+Title" it autoconverts it into a link with visible text: "CO:GD-0147" and pointing to "https://confluence.example.com/pages/createpage.action?spaceKey=~username&title=My+Page+Title&linkCreation=true&fromPageId=15522507".
