It Depends (tm). In this case on how sophisticated/precise your users are. If your users are exclusively extremely conversant in the language and are expected to have keyboards that allow easy access to all the accents… then I might leave them in. In some cases removing them can change the meaning of a word.
That said, most installations I’ve seen remove them. They’re still present in any returned stored field so the doc looks good. And then you bypass all the nonsense about perhaps ingesting a doc that “somehow” had accents removed and/or people not putting accents in their search and the like.
