编程语言里的转义字符真的叫转义字符吗？

我们先来看看别人是怎么说转义字符的？

 

 这是我随便从两本书上截图来的，总的来说就是反斜杠加几个字符就是转义字符。

就问你晕不晕，斜杠加几个字符至少是两个字符，那还叫字符吗，那叫字符串吧，怎么取名转义字符？

于是我找外文是怎么说的。下图就是我找的外文：

然后我摘了几句如下： 

In our greeting string, we can see the \ndigraph, which represents the character to be output to the console.

从上面可以看出\n叫digraph。

Digraphs that appear in strings are also called escape sequences。

从上面可以看出digraph叫转义字符序列。

Even though escape sequences appear as two characters, they are actually a single, non-visible character. 

从上面可以看出转义序列以两个字符形式出现。

通过以上分析我们所说的转义字符其实叫转义字符序列，这样就通了。
