test case

No problem with trunk on Arch Linux.
The font matching has changed with 4.7, I wonder if that is related.

My trunk dates from 03-31 and it works as expected.

I had seen this issue some time back in other platform & it was root caused to the ttf file missing this unicode. I don't remember the detailed analysis but the width/height was not coming properly for this unicode & therefore the issue.
