Screenshot of empty spaces in the special characters dialog

The "Special Characters" dialog contains a grid of characters at the bottom of which are a lot of empty squares (where characters would normally be present).

Steps to Reproduce:

1. Open Libreoffice Writer.
2. Click on the "Special Characters" button in the toolbar.
3. Scroll down to the bottom of the symbols grid.

Current Behaviour:

There are many blank/empty squares towards the bottom of the symbols grid.

Expected Behaviour:

The user should only be able to scroll down to the last symbol in the grid and no further.

I have attached a screenshot to show the problem. As can be seen in the screenshot I only scrolled about 3/4 of the way down and the rest were all empty squares. I am not sure whether this was done intentionally but it seems a bit strange to have lots of empty space for the user to scroll through.

Tested with Libreoffice:

Version: 4.4.0.0.alpha2+

This bug has long been present, but now is more evident. In previous versions I could only reproduce it in a low-end, old computer running Windows XP.

I rather suspect that the count of chars from FontCharMap::GetCharCount is wrong somehow
