测试成功，楼主结贴给分吧

Java code

    String str = "跳舞鞋红色亲子鞋215BRAND:足下有福";
    Pattern pattern = Pattern.compile("(&#(\\p{XDigit}{5});)");    
        Matcher matcher = pattern.matcher(str);    
        char ch;    
        while (matcher.find()) {
            ch = (char) Integer.parseInt(matcher.group(2));     
            str = str.replace(matcher.group(1), ch + "");
        }    
        System.out.println(str);

        //输出结果为：跳舞鞋红色亲子鞋215BRAND:足下有福

ldh911 大神始终快我一些啊

另外unicode 是把字符编译为16进制的 类似

楼主要处理的字符串其实不是普通的unicode编码 而是&# + ascii +";" 的html实体符号

中文“足” 的unicode为 “\u8db3” 而楼主的是 “足”

也就是16进制和10进制的区别

------解决方案--------------------

足  这种是html entity中的decimal character reference

也可以利用现成的jakarta commons lang包
比如commons-lang-2.6.jar

Java code

import org.apache.commons.lang.StringEscapeUtils;

public class Test {

    public static void main(String[] args) {
        System.out.println(StringEscapeUtils.unescapeHtml("足"));
        System.out.println(StringEscapeUtils.unescapeHtml(""));
    }

}

JScript code


alert(String.fromCharCode(36275,19979,26377,31119));
