Bug Description
All Ubuntu fonts have missing some kerning pairs of letters with diacritics. Capital "T", "V" and "P" together with "o", "e" and "a" have different distances between letters with and without diacritics. It seems that some of the letters have no preconfigured kerning.
Please see attached PDF file.

Can you tell us what application this PDF was originally created on please.
It may be that this application does not use 'GPOS' kern table information for kerning glyphs, but uses the more simplified 'kern' font table. Only the GPOS kern tables will hold the full kerning information for the font, including the accented glyphs. A non-GPOS table (called 'kern') holds a limited amount of kerning information for applications that do not access the GPOS kern information. This table however is limited in its format and maximum size so cannot hold kerning information for all the glyphs in the font.
