我怎么能从java中删除一个字符串的阿拉伯标点符号
我正在写阿拉伯语字典，我得到的句子就像
String original =“’أبنفلانا：عابهورماهبخلةسوء。’”; 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
为什么不直接使用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 = "'أَبَنَ فُلانًا: عَابَه ورَمَاه بخَلَّة سَوء.'"; 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: أ ب ن ف لان ا ع اب ه ور م اه بخ ل ة س وء
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 。
试试这个代码 ，它在我的项目中工作正常：

我发现这样做要好得多。 非常感谢joop的提示。
import java.text.Normalizer; import java.text.Normalizer.Form; /** * * @author Ibbtek
你可以用这个：
String withDiacritics = "طَائِفِيّةٌ"; String withoutDiacritics = withDiacritics.replaceAll("(ّ)?(َ)?(ً)?(ُ)?(ٌ)?(ِ)?(ٍ)?(~)?(ْ)?", "");
输出将如下：“طائفية”。
就我而言，这个解决方案正在运行。 我尝试了很多解决方案，但没有一个正常工作。
String diacless = Normalizer.normalize(textWithDiacritics, Normalizer.Form.NFKD).replaceAll("\\p{M}", ""); Log.d("diac_remove", "replaced: "+diacless);
