Ruby/Rails : How to remove all the unicode in a string?

I have a lot of records in a legacy database and I need to export that data into a CSV using the ISO-1889-1 format because there are spanish characters.

However, when converting it to utf-8 to iso, it keeps throwing errors of not being able to convert certain characters. ex:

Encoding::UndefinedConversionError - U+2026 from UTF-8 to ISO-8859-1

this happens at this line in my controller:

send_data(data.encode("iso-8859-1"), filename: "books_data_#{date}.csv", type: 'text/csv; charset=iso-8859-1; header=present')

To fix this individual issue I just did string.gsub!("…", ""). Is there a more universal way to just remove all unicode in a ruby string? Doing it by hand for each one that appears is not as complete, ugly, and hard to maintain if new unicode characters arise. Just wondering.

Are you looking for String::encode?

irb(main):011:0> "Здравствуйте Stack Overflow!".encode("iso-8859-1", undef: :replace, replace: "")
=> " Stack Overflow!"
