提问by lacas
Possible Duplicates:
Remove diacritical marks (ń ? ň ? ? ? ? ? ? ? ? ? ? ? ?) from Unicode chars
Is there a way to get rid of accents and convert a whole string to regular letters?
可能的重复项：
从 Unicode 字符中删除变音符号 (ń ? ň ? ? ? ? ? ? ? ? ? ?)
有没有办法摆脱重音并将整个字符串转换为常规字母？
How can i do this? Thanks for the help

I think your question is the same as these:
我认为你的问题与这些相同：
and hence the answer is also the same:
因此答案也是一样的：
String convertedString =
Normalizer
.normalize(input, Normalizer.Form.NFD)
.replaceAll("[^\p{ASCII}]", "");
See
看
- JavaDoc: Normalizer.normalize(String, Normalizer.Form)
- JavaDoc: Normalizer.Form.NFD
- Sun Java Tutorial: Normalizer's API)
- JavaDoc: Normalizer.normalize(String, Normalizer.Form)
- JavaDoc：Normalizer.Form.NFD
- Sun Java 教程：Normalizer 的 API）
Example Code:
示例代码：
final String input = "T??? ?? a f?ň?? ????ń?";
System.out.println(
Normalizer
.normalize(input, Normalizer.Form.NFD)
.replaceAll("[^\p{ASCII}]", "")
);
Output:
输出：
This is a funky String
这是一个时髦的字符串

First - you shouldn't. These symbols carry special phonetic properties which should not be ignored.
首先 - 你不应该。这些符号带有特殊的语音特性，不应被忽略。
The way to convert them is to create a Mapthat holds each pair:
转换它们的方法是创建一个Map包含每一对的：
Map<Character, Character> map = new HashMap<Character, Character>();
map.put('á', 'a');
map.put('é', 'e');
//etc..
and then loop the chars in the string, creating a new string by calling map.get(currentChar)
然后循环字符串中的字符，通过调用创建一个新字符串 map.get(currentChar)

You can use java.text.Normalizerto separate base letters and diacritics, then remove the latter via a regexp:
您可以使用java.text.Normalizer分隔基本字母和变音符号，然后通过正则表达式删除后者：
public static String stripDiacriticas(String s) {
return Normalizer.normalize(s, Form.NFD)
.replaceAll("\p{InCombiningDiacriticalMarks}+", "");
}
