Tintin and Asterix are pretty popular in the UK and India. Easily found in most bookshops. Beyond those series, it’s much harder to find other Franco-Belgian comics. Even the Adventures of Jo and Zette isn’t that well known.

But Tintin and Asterix are very easily available. India has local language translations of Tintin and Asterix as well, example[1].

Anecdotally the quality of the Asterix translations are pretty good, too, complete with the funny character names.
