-> Tip We recommend the [`iconv` command-line tool](https://linux.die.net/man/1/iconv) to convert files with encodings not supported by `read_csv` to UTF-8. For example:
+> Tip DuckDB's CSV reader supports UTF-8 (default), UTF-16 and Latin-1 encordings (see the `encoding` option).
+> To convert files with different encodings, we recommend using the [`iconv` command-line tool](https://linux.die.net/man/1/iconv).
