从不包含非拉丁字符的字符串中删除所有特殊字符 [英] Remove all special characters from a string not including non-latin characters

问题描述

我想删除字符串中除数字和普通az字符之外的所有特殊字符。

I want to remove all the special characters from a string except numbers and normal a-z characters.

我这样做：

text = text.replaceAll("[^a-zA-Z0-9 ]+", "");

这种方式的问题是它还会删除所有非拉丁字符，如è，é， ê，ë和其他许多人。

The problem with this way is that it will also remove all non-latin characters like è, é, ê, ë and many others.

非特殊字符（我要保留的字符）是指所有语言的所有数字和所有字母字符或至少尽可能多。

By non-special characters (the ones I want to keep) I mean all the numbers and all the alphabetical characters for all the languages or at least as many as possible.

我如何只删除特殊字符？

How do I only remove the special characters?

推荐答案

您可以尝试 \p {L} 获取所有字母， \p {N} 对于所有数字：

You can try \p{L} for all letters and \p{N} for all numbers:

text = text.replaceAll("[^\\p{L}\\p{N} ]+", "");
