Most television series only have to deal with one spoken language — maybe two or three. The mystery thriller #Netflix1899 juggles up to seven different languages in a given episode.
Some think #dubbing doesn't work, "it's the wrong way to watch it."

Example of viewers' comments:
"There are several characters speaking different languages while not understanding each other. In dubbed versions they all speak the same language so the dialogues are changed because it would be pretty absurd otherwise."

Example of languages tagged in SDH (end of Ep1)

Each language has a different strategy: Greek omits, Spanish transcribes.
Proof that multilingualism wasn't addressed in the showguide / or was not followed?

German translates (Italian as well) Portuguese omits
(my mind full of hypotheses!😅)
