我怎么能从java中删除一个字符串的阿拉伯标点符号

Question

我正在写一本阿拉伯语字典,我得到像
String original ="'أبنفلانا:عابهورماهبخلةسوء.'"这样的句子.从我的数据库,但我无法处理句子而不删除重音和标点符号

我试过用

import java.text.Normalizer;
import java.text.Normalizer.Form;
import java.util.regex.Pattern;

public static String deAccent(String str) {
    String nfdNormalizedString = Normalizer.normalize(str, Normalizer.Form.NFD); 
    Pattern pattern = Pattern.compile("\\p{InCombiningDiacriticalMarks}+");
    return pattern.matcher(nfdNormalizedString).replaceAll("");
} 

但它没有用

试试这个代码，它在我的项目上运行良好：

/**
 * ArabicNormalizer class
 * @author Ibrabel <ibrabel@gmail.com>
 */
public final class ArabicNormalizer {

    private String input;
    private final String output;

    /**
     * ArabicNormalizer constructor
     * @param input String
     */
    public ArabicNormalizer(String input){
        this.input=input;
        this.output=normalize();
    }

    /**
     * normalize Method
     * @return String
     */
    private String normalize(){

        //Remove honorific sign

你为什么不去寻找Unicode标点/标记,非间距类别？

不确定您的预期结果,因为它没有发布 - 我无法阅读阿拉伯语:),但请尝试以下代码:

String input = "'?????? ???????: ?????? ??????? ??????? ????.'";
Pattern p = Pattern.compile("[\\p{P}\\p[Mn]");
Matcher m = p.matcher(input);
while (m.find()) {
    System.out.println("found: " + m.group());
}
m.reset();
System.out.println("Replaced: " + m.replaceAll(" "));

输出:

found: '
found: ?
found: ?
found: ?
found: ?
found: ?
found: :
found: ?
found: ?
found: ?
found: ?
found: ?
found: ?
found: ?
found: ?
found: .
found: '
Replaced:  ? ? ?  ? ??? ?  ? ?? ? ?? ? ?? ?? ?  ? ? ??  

我想这不是你想要的最终结果,但我希望你可以使用它.

此外,这是关于Unicode类别的信息的金矿.我相信大多数都适用于Java Pattern.
