[DejaVu-fonts] Character D

[a s. <asw...@ho...>]

I have found 2 characters which I can use for my transliteration which I am working on. 

Capital D with stroke  U+0110
Roman numeral five hundred. U+216E

Both do not take the circle above properly. And only the first one exists in italics. 

I would be grateful if the above could be fixed. 
Thanks
