Many characters used in African languages orthographies a currently missing 
from the Ubuntu font family.
Some are actually present in uppercase, for example Ɛ U+0190 is present but ɛ 
U+025B is missing.
Combining diacritics (U+0300, etc. and U+1DC4...1DC7) are also needed as many 
African languages use them.

For the combining diacritics, OpenType GPOS features need to be added
for correct positioning.

Examples:
ɛ U+025B and ɔ U+0254 are used in the official alphabets of Benin, Burkina 
Faso, Mali, Tchad, and Cameroon, as well as other alphabets.
U+300 is used in the Pan-Nigerian alphabet (in Yoruba ẹ́ is used), or in any 
language using accented characters not in Unicode as precomposed form.

The ANLoc (African localisation) project has a list of characters uses in 
orthographies of African languages :

and a list of accented characters (not available as precomposed characters, 
i.e. using combining diacritics)
