Wikipedia:Articles for deletion/Andar Char
It does appear to be a legally recognized populated place, given its listing in census documents (https://books.google.com/books?id=pLlGsDq4MgEC&q=%22andar+char%22&dq=%22andar+char%22&hl=en&newbks=1&newbks_redir=1&printsec=frontcover&sa=X&ved=2ahUKEwiBiafrgLzxAhXglWoFHW3oAcUQ6AEwBHoECAkQAg This one, for example), although I can only view them through Google Books snippet view so I can't tell what those documents are saying about the place. Besides that, https://books.google.com/books?id=NKjYAAAAMAAJ&q=%22andar+char%22&dq=%22andar+char%22&hl=en&newbks=1&newbks_redir=1&printsec=frontcover&sa=X&ved=2ahUKEwiBiafrgLzxAhXglWoFHW3oAcUQ6AEwBXoECAoQAg this source from 1932, also from snippet view describes it as an island serving as "a centre of fish-trade", and https://www.google.com/books/edition/Land_Solutions_for_Climate_Displacement/v9OhAwAAQBAJ?hl=en&gbpv=1&dq=%22andar+char%22&pg=PA139&printsec=frontcover this one lists it as an island as well as further describing what a "char" is. Those aren't exactly significant coverage, but they could help flesh out the article a little. Altogether it looks like this place just barely squeaks by due to  but I'm fine keeping based on that
