I came across some regular expressions that I've never seen before, and I can't find any information on what they do. Here's an example:
我遇到了一些我以前从未见过的正则表达式，我找不到它们的任何信息。这里有一个例子:
/[\p{Z}\p{Cc}\p{Cf}\p{Cs}\p{Pi}\p{Pf}]/u
I'm looking for a full reference for regex.
我在寻找regex的完整参考资料。
P.S. I think the example provided only words in certain languages. It works in PHP but not Javascript.
附注:我认为这个例子只提供了某些语言的词汇。它使用PHP而不是Javascript。
