c# - 如何通过 GSM 调制解调器使用 AT 命令在 C# 中读取 Unicode 消息(例如波斯语和阿拉伯语)？

Question

我阅读这篇文章是为了发送 Unicode 短信，但我想知道如何读取 utf8 短信？

Sending Unicode Messages (such as in Persian and Arabic) in C# using AT Commands through GSM Modem

我发送了这个命令，但收到的消息文本是这样的:

 AT+CMGL="ALL"

  +CMGL: 1,"REC READ","97563937625","","2013/08/28 00:53:30+18"
     0041006A006D0064006A00740020

我读取短信的命令:

          ExecCommand(port,"AT", 300, "No phone connected");

            ExecCommand(port,"AT+CSCS=\"UCS2\"\n", 300, "No phone connected");

            ExecCommand(port,"AT+CMGF=1", 300, "Failed to set message format.");

            ExecCommand(port,"AT+CPMS=\"MT\"", 300, "Failed to select message storage.");          

            string input = ExecCommand(port, "AT+CMGL=\"ALL\"", 5000, "Failed to read the messages.");

    private string decoder(string value)
    {
        Regex lettersOnly = new Regex("^[0-9]|[A-Z]$");
        if ((value.Length % 4 == 0) && lettersOnly.Match(value).Success)
        {
            string data = FromHex(value);

            return data;
        }
        else
            return value;
    }      

    public static string FromHex(string hex)
    {
        short[] raw = new short[hex.Length / 4];
        for (int i = 0; i < raw.Length; i++)
        {
            raw[i] = Convert.ToInt16(hex.Substring(i * 4, 4), 16);
        }
        string s = "";
        //wtf encoding utf32 ride ahmagh kos sher pas mide
        foreach (var item in raw)
        {
            s += char.ConvertFromUtf32(item).ToString();
        }
        return s;
    }
