What is UTF-8 encoding used for?

UTF-8 is the most widely used way to represent Unicode text in web pages, and you should always use UTF-8 when creating your web pages and databases. But, in principle, UTF-8 is only one of the possible ways of encoding Unicode characters.

What are UTF-8 codes?

UTF-8 is the universal code page for internationalization and is able to encode the entire Unicode character set. It is used pervasively on the web, and is the default for *nix-based platforms. An encoded character takes between 1 and 4 bytes.

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

Wikipedia explains both reasonably well: UTF-8 vs Latin-1 (ISO-8859-1). Former is a variable-length encoding, latter single-byte fixed length encoding. Latin-1 encodes just the first 256 code points of the Unicode character set, whereas UTF-8 can be used to encode all code points.

What is the difference between UTF-8 and UTF-16?

Utf-8 and utf-16 both handle the same Unicode characters. They are both variable length encodings that require up to 32 bits per character. The difference is that Utf-8 encodes the common characters including English and numbers using 8-bits. Utf-16 uses at least 16-bits for every character.

How to save an UTF-8 encoded text file?
