UTF-8 Encoding

8-bit Unicode Transformation format, called UTF-8, is a variable width character encoding that can encode all of the 1.111.064 valid code points in Unicode wit one to four 8-bit bytes. The number "8" means 8-bit blocks are used by UTF for representing a character.

Since 2009, UTF-8 has been the leading encoding for the World Wide Web.

For characters that are equal to or below 127 (hex 0x7F), the UTF-8 representation is one byte. This is similar to the ASCII value.

For any character equal to or below 2047 (hex 0x07FF), the UTF-8 representation is scattered over two bytes.

For any character that is equal to or greater than 2048 but less than 65535 (0xFFFF), the UTF-8 representation will be spread across three bytes.

The list below shows some UTF-8 character codes which are supported by HTML5:
