正则表达式可以与其他语言一起使用吗? [英] Can regular expressions work with different languages?

问题描述

当然，英语对regex毫无疑问，因为它最初是在以下语言/中开发的:

English, of course, is a no-brainer for regex because that's what it was originally developed in/for:

正则表达式可以理解此字符集吗?

Can regular expressions understand this character set?

法语遇到了一些重音符号，我不确定该如何与之匹配-即è和e都被正则表达式视为单词字符?

French gets into some accented characters which I'm unsure how to match against - i.e. are è and e both considered word characters by regex?

Les Expressionsrégulièrespeuvent comprendre ce jeu decaractères?

Les expressions régulières peuvent comprendre ce jeu de caractères?

日语不包含我所知道的与之匹配的正则表达式文字字符.

Japanese doesn't contain what I know as regex word characters to match against.

距离表现は，この文字を理解でき，设定?

正規表現は、この文字を理解でき、設定？

推荐答案

简短答案:是.

具体来说，这取决于您的正则表达式引擎是否支持unicode匹配(如此处所述).

More specifically it depends on your regex engine supporting unicode matches (as described here).

此类匹配会极大地使您的正则表达式复杂化，因此我建议阅读此 unicode regex教程(还请注意，Unicode实现本身可能很混乱，因此您也可以从阅读Joel Spolsky的有关字符集内部工作的文章).

Such matches can complicate your regular expressions enormously, so I can recommend reading this unicode regex tutorial (also note that unicode implementations themselves can be quite a mess so you might also benefit from reading Joel Spolsky's article about the inner workings of character sets).
