# ISO/IEC 646

**ISO/IEC 646:1991**，即“信息技术：ISO信息交换七位编码字集”，是国际标准化组织（ISO）搭国际电工委员会（IEC）制订个标准。1972年用几隻国家标准搭拕来个七位字符代码制订初版。

由于ISO/IEC 646所有国家共有个部分只指定仔现代基本拉丁字母，别个国家用扩充拉丁字母来书写该国语言就要造隻ISO 646个国家变体。又由于当时八位个字节朆得到普遍个接纳，箇眼国家变体标准里个字符要受七位个约束，就是话ASCII里有眼字符勿会得来拉别个国家个 ISO 646 变体里向出现。

ECMA也批准仔ISO/IEC 646，即ECMA-6。

下头隻表格显示ISO/IEC 646字集。每隻字符附仔渠个十进制代码搭Unicode等价物。灰底单格表明隻码点浪个字符各地勿一样，下头会得详细讨论个。

## ASCII 个变体（非ISO 646）

还有眼七位字集勿是ISO 646标准正式个一部分。譬方：

* 七位希腊字母，ELOT 927。
* 七位基里尔字母，KOI-7 或者 Short KOI。
* 七位希伯来字母，SI 960。
* 七位阿拉伯字母，ASMO 449。
