ASCII码表 信息在计算机上是用二进制表示的，这种表示法让人理解就很困难。因此计算机上都配有输入 和输出设备，这些设备的主要目的就是，以一种人类可阅读的形式将信息在这些设备上显示出 来供人阅读理解。为保证人类和设备，设备和计算机之间能进行正确的信息交换，人们编制的 统一的信息交换代码，这就是ASCII码表，它的全称是“美国信息交换标准代码”。 八进制 00 01 02 03 04 05 06 07 10 11 12 13 14 15 16 17 20 21 22 23 十六进制 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10 11 12 13 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 十进制 字符 nul soh stx etx eot enq ack bel bs ht nl vt ff er so si dle dc1 dc2 dc3 八进制 100 101 102 103 104 105 106 107 110 111 112 113 114 115 116 117 120 121 122 123 十六进制 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50 51 52 53 十进制 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 @ A B C D E符

汉字编码表

汉字编码表

汉字编码表汉字编码表是指unicode字符集中所包含的汉字及其拼音、笔画等一系列特征信息的列表。

以此表为基础，我们可以方便地在计算机中处理、输入和输出汉字文字。

下面是关于汉字编码表的详细介绍。

一、汉字编码的历史汉字编码的历史可以追溯到计算机问世之初，当时的计算机只能处理英文字符，汉字是不能够被计算机处理的。

为了解决这个问题，人们想出了一种叫做“汉字编码”的方法，将汉字转换为计算机可以识别的数字代码，从而实现汉字文字的输入输出。

汉字编码最早的版本是中国国家标准GB2312，于1980年发布，其中包含了6763个常用汉字，以及682个生僻汉字和符号。

但后来随着社会的发展，汉字数量不断增加，GB2312编码已经无法满足需求，于是便出现了GBK编码、GB18030编码等新版本。

二、汉字编码表的结构汉字编码表通常由三个部分组成：区码、位码和字符描述信息。

区码是汉字编码的一个重要部分，它用于表示汉字所在的区域。

GB2312编码中，共分为94个区，每个区由一组汉字组成，区码范围从A1至F7，每个区包含94个位码，共计8836个字符。

GBK编码中，共分为126个区，其中94个区与GB2312编码相同，另外32个区包含了1600个生僻汉字和符号。

区码范围从81至FE。

GB18030编码共分为257个区，其中126个区与GBK编码相同，另外131个区包含了7万多个汉字。

位码是汉字编码表中的另一个重要部分，它用于表示汉字在所在区中的位置。

每个区包含94个位码，位码范围从A1至FE。

可以看出，位码的数量决定了一个区所能包含的汉字数量，也决定了汉字编码表的容量大小。

字符描述信息的主要包括汉字的拼音、笔画和部首等信息。

其中拼音用于输入法输入汉字，笔画、部首等信息可以用于汉字检索等功能。

三、常用汉字编码表1、GB2312编码表GB2312编码表是最早的汉字编码表，它包含了所有的常用汉字，共6763个。

在GB2312编码表中，区码范围从A1至F7，每个区共计94个位码。
