        string input = "Hello, 世界!";
        string output = RemoveUnicodeCharacter(input, '\u4E16'); // 删除Unicode字符'世'
        Console.WriteLine(output); // 输出：Hello, !
    }

    {
        char[] charArray = input.ToCharArray();
        int index = 0;

        for (int i = 0; i < charArray.Length; i++)
        {
            if (charArray[i] != unicodeChar)
            {
                charArray[index++] = charArray[i];
            }
        }
