Accents for d, t, l are too large and therefore also kerning with subsequent character is off

[athelas64]

Accented ď, ť, ľ breaks the flow, because a) accents are too big (should be around 75% of the size) and b) because of their size, the kerning is broken (with the letter ť even looking thicker than t)
The kerning pairs should share the same distance between accented and non accented versions of d, t, l
As a consequence, the longer text typeset in Roboto using the aforementioned characters looks uneven.

Just to add to the fact, that this indeed is an error, all other variants (Roboto Condens, Roboto Mono and Roboto Slab) do not have this issue.
