What is the difference between UTF-8 and ISO-8859-1?

Most libraries that don't hold a lot of foreign language materials will be perfectly fine with ISO8859-1 ( also called Latin-1 or extended ASCII) encoding format, but if you do have a lot of foreign language materials you should choose UTF-8 since that provides access to a lot more foreign characters.
As of July 2022, 1.2% of all (but only 5 of the top 1000) websites use ISO/IEC 8859-1. It is the most declared single-byte character encoding in the world on the web, but as web browsers interpret it as the superset Windows-1252 the documents may include characters from that set.
Going backwards from UTF-8 to ISO-8859-1 will cause "replacement characters" (�) to appear in your text when unsupported characters are found. byte[] utf8 = ... byte[] latin1 = new String(utf8, "UTF-8"). getBytes("ISO-8859-1"); You can exercise more control by using the lower-level Charset APIs.
what is the difference between utf8 and latin1? They are different encodings (with some characters mapped to common byte sequences, e.g. the ASCII characters and many accented letters). UTF-8 is one encoding of Unicode with all its codepoints; Latin1 encodes less than 256 characters.
UTF-8 is a multibyte encoding that can represent any Unicode character. ISO 8859-1 is a single-byte encoding that can represent the first 256 Unicode characters. Both encode ASCII exactly the same way.
