Comment 3 for bug 939439

We could possibly add a new char in the ubuntu font to cover this case, but I'm not sure and it's just a possibility.
Even if it's not something that can be directly fixed in unity, now we still need to keep the bug opened to have it on track, otherwise it will get lost in the long list of 'Invalid' bugs.
The product which shows the bug is unity, in fact, so I don't know why we were closing the bug.
