正则表达式删除非字母字符但保留重音字母 [英] Regex to remove non-letter characters but keep accented letters

问题描述

我有西班牙语和其他语言的字符串，可能包含通用特殊字符，如（），*等。我需要删除。但问题是它也可能包含特殊的语言字符，如ñ，á，ó，í等，它们需要保留。所以我试图用以下方式用regexp来做：

I have strings in Spanish and other languages that may contain generic special characters like (),*, etc. That I need to remove. But the problem is that it also may contain special language characters like ñ, á, ó, í etc and they need to remain. So I am trying to do it with regexp the following way:

var desired = stringToReplace.replace(/[^\w\s]/gi, '');

不幸的是，它删除了所有特殊字符，包括相关语言。不知道如何避免这种情况。也许有人可以建议？

Unfortunately it is removing all special characters including the language related. Not sure how to avoid that. Maybe someone could suggest?

推荐答案

我建议使用Steven Levithan的优秀 XRegExp 库及其 Unicode插件。

I would suggest using Steven Levithan's excellent XRegExp library and its Unicode plug-in.

这是一个从字符串中删除非拉丁字符的例子： http://jsfiddle.net/b3awZ/1/

Here's an example that strips non-Latin word characters from a string: http://jsfiddle.net/b3awZ/1/

var regex = XRegExp("[^\\s\\p{Latin}]+", "g");
var str = "¿Me puedes decir la contraseña de la Wi-Fi?"
var replaced = XRegExp.replace(str, regex, "");
