Java:如何删除出现在Â之前的字符

public class Main {
    public static void main(String[] args) {
        String input = "Some text before  and some after.";
        char charToDeleteBefore = 'Â';

        String result = deleteBeforeChar(input, charToDeleteBefore);
        System.out.println(result); // 输出: "Â and some after."
    }

    public static String deleteBeforeChar(String input, char charToDeleteBefore) {
        int index = input.indexOf(charToDeleteBefore);
        if (index == -1) {
            // 如果字符不存在，返回原始字符串
            return input;
        } else {
            // 否则，返回该字符及其之后的所有字符
            return input.substring(index);
        }
    }
}
