我试图弄清楚所有这些 \e6 ##引用的含义。

I'm trying to figure out what all these "\e6##" references mean. Is "\e" some sort of special character?

.icon-logo-mark:before {
    content: "\e601";
}
.icon-burger:before {
    content: "\e602";
}
.icon-arrow-down:before {
    content: "\e603";
}

推荐答案

简单地说，它们是Unicode参考。例如， \e601是十六进制代码0xe601。如果您转到此处： http://unicodelookup.com/#0xe601/1 ，您会看到该字符的条目完全空白。它属于Unicode字符集的一部分，仅供私人使用。含义图标库等可以将所需内容放置在这些位置，而不必担心会覆盖诸如世界上任何一个字母或汉字这样的通用字符。

Put simply, they're Unicode references. The "\e601", for example, is the hex code 0xe601. If you go here: http://unicodelookup.com/#0xe601/1 you'll see that the entry for that character is totally blank. It's in a part of the Unicode character set reserved for "private" use. Meaning icon libraries and the like can place whatever they want in those spots and not have to worry about overriding common characters like those of any of the alphabets of the world or a Chinese character, for instance.
