正确的磅符号ASCII值 [英] Correct ASCII value of Pound sign

问题描述

我正在检查英镑符号(£)的ASCII值.我找到了多个答案:

I am checking for the ASCII value of the pound sign (£). I've found multiple answers:

1. http://www.ascii-code.com/说A3 = 163是ASCII码英镑符号的值.
2. http://www.asciitable.com/说156是英镑符号，而163是其他符号字符.
3. http://en.wikipedia.org/wiki/Pound_sign :Alt + 163表示和Alt + 156都是在美式键盘中输入井号的方法.我在这里假设163和156表示ASCII值. (但只有163个对我有用)

1. http://www.ascii-code.com/ Says A3 = 163 is the ASCII value of the pound sign.
2. http://www.asciitable.com/ Says 156 is the Pound sign and 163 is some other character.
3. http://en.wikipedia.org/wiki/Pound_sign : Says Alt+163 and Alt+156 both are the ways to type pound sign in US keyboard. I assume here 163 and 156 means ASCII values. (But only 163 works for me)

正确的方法是什么?

推荐答案

井号没有ASCII码. ASCII仅在您链接的表中定义代码0-127；而在链接表中仅定义0-127.除此之外的所有东西都是扩展.您需要确定所使用的ASCII扩展名.

There is no ASCII code for the pound sign. ASCII only defines codes 0-127 in the tables you've linked; everything beyond that is extensions. You'll need to determine which extension to ASCII you're using.

英镑符号在Latin-1(又名ISO-8859-1)中为163，在代码页437 .它也有Unicode编号163，尽管您需要将其编码为一个以上的字节.

The pound sign has number 163 in Latin-1 (aka ISO-8859-1), and number 156 in code page 437. It also has number 163 in Unicode, though you'll need to encode it as more than one byte.
