            Bug ID: 51508
           Summary: POTD Title returned by expandtemplates is not correct.
           Product: MediaWiki
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Unprioritized

I am using the Wiki API for accessing the entire Wiki.

When I am calling the following API;
http://en.wikipedia.org/w/api.php?action=expandtemplates&format=json&text={{POTD/{{#time:Y-m-d}}|title}}
I get the following output;
{
    "expandtemplates": {
        "*": "''[[A Wheat Field with Cypresses]]''"
    }
}
which I use in the next API as follows to get the actual image for this title. 
http://en.wikipedia.org/w/api.php?action=query&prop=pageimages&piprop=thumbnail|name&pithumbsize=240&format=json&redirects=&titles=A%20Wheat%20Field%20with%20Cypresses

But it seems the title contains an additional "A" because of which it gives me
missing element.
{
    "query": {
        "pages": {
            "-1": {
                "ns": 0,
                "title": "A Wheat Field with Cypresses",
                "missing": ""
            }
        }
    }
}
But if I remove "A" from the title it gives me proper details as follows;
{
    "query": {
        "pages": {
            "27773473": {
                "pageid": 27773473,
                "ns": 0,
                "title": "Wheat Field with Cypresses",
                "thumbnail": {
                    "source":
"https://upload.wikimedia.org/wikipedia/commons/thumb/7/7d/Vincent_Willem_van_Gogh_049.jpg/240px-Vincent_Willem_van_Gogh_049.jpg";,
                    "width": 240,
                    "height": 191
                },
                "pageimage": "Vincent_Willem_van_Gogh_049.jpg"
            }
        }
    }
}

This is breaking my Web App which I am developing as the title returned by API
is incorrect. Please let me know if this is an actual bug or the title entered
is incorrect or I am making a mistake somewhere.

Thanks and Regards,
Harin
