UTF-8 Encoding

UTF-8 Encoding （루bits£©）

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. （8位Unicode转换格式，称为UTF-8 ，是一种可变宽度字符编码，可以用一到四个8位字节对Unicode中的所有1.111.064有效代码点进行编码。数字“8”表示UTF使用8位块来表示字符。）

Since 2009, UTF-8 has been the leading encoding for the World Wide Web. （自2009年以来， UTF-8一直是万维网的领先编码方式。）

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. （对于等于或低于127 （十六进制0x7F ）的字符， UTF-8表示为一个字节。这与ASCII值类似。）

For any character equal to or below 2047 (hex 0x07FF), the UTF-8 representation is scattered over two bytes. （对于等于或低于2047的任何字符（十六进制0x07FF ） ， UTF-8表示分散在两个字节上。）

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. （对于等于或大于2048但小于65535 (0xFFFF)的任何字符， UTF-8表示将分布在三个字节中。）
