如何将拉丁 unicode 字符替换为 [a-z] 字符 [英] how to replace Latin unicode character to [a-z] characters

问题描述

我正在尝试将所有拉丁语 unicode 字符转换为它们的 [a-z] 表示

I'm trying to convert all Latin unicode Character into their [a-z] representations

ó --> o
í --> i

我可以很容易的一一做例如:

I can easily do one by one for example:

myString = myString.replaceAll("ó","o");

但是由于有很多变化，这种方法是不切实际的

but since there are tons of variations, this approach is just impractical

在 Java 中还有其他方法吗?例如正则表达式，或工具库

Is there another way of doing it in Java? for example a regular Expression, or a utility library

用例:

1- 将其他语言的城市名称转换为英语，例如

1- city names from another languages into english e.g.

圣埃斯皮里图 --> 圣埃斯皮里托，

Espírito Santo --> Espirito Santo,

推荐答案

此答案需要 Java 1.6 或更高版本，其中添加了 java.text.Normalizer.

This answer requires Java 1.6 or above, which added java.text.Normalizer.

    String normalized = Normalizer.normalize(input, Normalizer.Form.NFD);
    String accentRemoved = normalized.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");

示例:

public class Main {
    public static void main(String[] args) {
        String input = "Árvíztűrő tükörfúrógép";
        System.out.println("Input: " + input);
        String normalized = Normalizer.normalize(input, Normalizer.Form.NFD);
        System.out.println("Normalized: " + normalized);
        String accentRemoved = normalized.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
        System.out.println("Result: " + accentRemoved);
    }
}

结果:

Input: Árvíztűrő tükörfúrógép
Result: Arvizturo tukorfurogep
