Where are keywords stored in db? OJS

Hi! There are strange characters in the keywords of the publications (spanish accents seem to be encoded). This only happens with keywords, all other things are displayed with the correct spanish chars.

We migrated to version 3.4 recently and I think the migration of the tables changed something in the encoding or at least is related with the issues. However, I’ve been exploring the db and found controlled_vocab_entry_settings table. I identified a keyword related to one of the affected publications. I edited the setting_value column. But when i refresh the frontend of the publication, the word is not changing, so I don’t know if that is the table OJS uses to retrieve the keywords (btw I see no relation between controlled_vocavs and publication/submission).

Is there any other table(s) that OJS actually uses for keyword metadata?
