I've hijacked a previous post, as this is problem is more widespread than the
original poster realized. Combining diacritics on all versions of DejaVu do not
place correctly for large or capital letters.  In addition, the tittle is not
removed on the lowercase "i" when a diacritic is added.  Attached PDF is from
Libreoffice/Linux showing the worst offeders.  On Windows/MSOffice, Aigue and
Grave (u0300 and u0301) place correctly on only the simple vowels (AEIOU), but
not the rest of the raised diacritics.  Compare to ttf-sil-charis (available in
universe) in the attached PDF, where they all place correctly.  

I would be excited to have DejaVu as an out-of-the-box font that would work
well for Cameroonian languages (mostly roman characters with the diacritics
listed in the pdf), but this issue is holding us back and keeping us using the
SIL fonts.  I was surprised not to find a reference to this already on
bugzilla. versions of DejaVu do not place correctly for large or capital
letters.  In addition, the tittle is not removed on the lowercase "i" when a
diacritic is added.  Compare to ttf-sil-charis (available in universe) in the
attached PDF, where they all place correctly.

Vertical placement is the priority, then we can talk horizontal placement.

I'm excited to see the complex diacritics like macron-grave included in the
list. We would be excited to have DejaVu as an out-of-the-box font that would
work well for Cameroonian languages (mostly roman characters with the
diacritics listed in the pdf), but this issue is holding us back and keeping
the country dependent on using our SIL fonts.

If this is something that must be done manually for letters and diacritics, I'm
willing to do some of the work myself if someone will point me in right the
direction or utility.
