Thus, whenever the shift character is encountered, the next character (or group of characters) identifies a new character set, and subsequent codes are interpreted as belonging to that set.
因此,每当遇到转移字符,就意味着接下来的字符(或字符组)来自一个新的字符集,接下来的字符就要用其所属的字符集自身的定义进行解释。
Another shift character in that set can be used to shift to a third set, which may again be the first set or a different set.
另一种转移字符还可以将字符转移到第三个字符集,这第3个字符集可以就是第一个字符集,也可以是另外一个。
You will notice that on a US keyboard, shift-4 is "$", which is the bash variable expansion character.
注意到了吗:在美国键盘上,shift-4 是 "$",它是 bash 变量扩展字符。
