ASCII
ASCII码表
ASCII码大致可以分作三部分組成。
第一部分是:ASCII非打印控制字符;
第二部分是:ASCII打印字符;
第三部分是:扩展ASCII打印字符。
第一部分:ASCII非打印控制字符表
ASCII表上的数字0–31分配给了控制字符,用于控制像打印机等一些外围设备。例如,12代表换页/新页功能。此命令指示打印机跳到下一页的开头。(参详ASCII码表中0-31)
第二部分:ASCII打印字符
数字 32–126 分配给了能在键盘上找到的字符,当您查看或打印文档时就会出现。数字127代表 DELETE 命令。(参详ASCII码表中32-127)

第三部分:扩展ASCII打印字符
扩展的ASCII字符满足了对更多字符的需求。扩展的ASCII包含ASCII中已有的128个字符(数字0–32显示在下图中),又增加了128个字符,总共是256个。即使有了这些更多的字符,许多语言还是包含无法压缩到256个字符中的符号。因此,出现了一些ASCII的变体来囊括地区性字符和符号。例如,许多软件程序把ASCII表(又称作ISO8859-1)用于北美、西欧、澳大利亚和非洲的语言。
