小编就为大伙带来了latin1的介绍,感兴趣的用户快来下文看看吧。
latin1和utf-8是一种编码形式,它们之间的区别在于:
一、编码方式不同
1、Latin1是8位单字节编码,用一个字节表示一个字符。由于只有256种可能的值,可以表示的字符也就只有256个,如英文字母、数字、罗马字母和某些符号,不能表示非拉丁字母的字符,比如汉字、日文字符等。
2、UTF-8是一种多字节编码,它可以根据字符的复杂度选择1~4个字节的表示方式,而且欧洲的拉丁字母也可以用1个字节表示,因此它支持绝大多数字符。
二、编码格式不同
1、Latin1采用ISO/IEC 8859-1中定义的编码格式,每一个字符都用8个比特(Bit)编码,通常是一个字节(Byte),有256个字符。
2、UTF-8采用Unicode标准编码,实际上是一种变长的编码方式,它的编码范围是1个字节至4个字节,而且英文字母也可以编码为一个字节。
三、实际使用上的不同
1、Latin1是一种基本的编码方式,可以用来表示大多数拉丁文字,但不能表示其它语言中的字符,比如汉字等。
2、UTF-8支持更多的字符,而且可以同时表示多种语言,因此可以在国际互联网上传输任何语言的文字,也可以使用UTF-8来表示西方语言。
因此,从实际使用上看,latin1只能用于拉丁文字,而UTF-8则可以用于多种语言,更适合国际互联网上的传输。
(1)Definition of Latin1
Latin1 (or ISO-8859-1) is an 8-bit character encoding of the Latin alphabet used by several Western European languages. It is based on the original 1987 version of ISO-8859, also referred to as Latin-1.
(2)Development of Latin1
The development of Latin1 began in 1987 when the International Organization for Standardization (ISO) released the first version of ISO-8859. This was revised in 1989 and the second version, Latin1, was released. Latin1 replaced the original Latin-1 encoding and was used in ISO-8859-1 and Windows-1252. The Latin-1 encoding was used in many platforms, including DOS, Unix and Mac OS.
(3)Details of Latin1
Latin1 includes up to 256 characters and each character is encoded using an 8-bit value. This value is stored in a single byte and begins at decimal 33 and ends at decimal 255. It supports the Western European languages like English, French, German and Swedish, as well as a few other languages like Italian and Spanish.
(4)Character Repertoire
Latin1 includes the Roman alphabet, German umlauts, French accents marks, as well as a few symbols and control characters. It also supports the Euro currency symbol, which is encoded at decimal 164. There are several variations between different implementations of the Latin1 encoding, with some platforms dropping certain letters such as the Icelandic ð or adding other characters like the Euro sign.
