HanLP 中并没有直接的函数来判断给定字符是否是汉字或标点符号。但你可以使用Java的内置方法，结合Unicode编码范围，来实现这个功能。

以下是一种使用 Java 来判断字符是否为汉字或标点符号的方法：

public class Main {  
    public static void main(String[] args) {  
        System.out.println(isChinese('汉')); // 输出：true  
        System.out.println(isPunctuation('，')); // 输出：true  
    }  
    // 判断是否为汉字  
    public static boolean isChinese(char c) {  
        Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);  
        return (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS  
                || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS  
                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A  
                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B  
                || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION  
                || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS  
                || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION);  
    }  
    // 判断是否为标点符号  
    public static boolean isPunctuation(char c) {  
        int codePoint = Character.getType(c);  
        return codePoint == Character.OTHER_PUNCTUATION || codePoint == Character.INITIAL_QUOTE_PUNCTUATION  
                || codePoint == Character.FINAL_QUOTE_PUNCTUATION;  
    }  
}  

在上述代码中，isChinese(char) 方法用于判断一个字符是否是汉字，而 isPunctuation(char) 方法则用于判断一个字符是否是标点符号。
