Tarnac is a superfamily typeface, designed by Marc Rouault:

The roots of Tarnac can be found in a variety of 20th century French Egyptian models, both formal and informal–as featured in posters, newspaper headlines, and the classic French road signs plaques Michelin.

I love thick slab-serif typefaces and Tarnac has a modern take on it. Tarnac also supports Vietnamese, which is a huge plus.
