public static string SplitMessage(string content, int limit)
        {
            int count = 0;
            int i = 0;

            for (i = 0; i < content.Length && count < limit * 2; i++)
            {
                if (content[i] < 0x80)
                {
                    count++;
                }
                else
                {
                    count += 2;
                }
            }

0x80是什么概念？

谢谢·高手们··
