How to get correct string text?

Question

I'm trying to obtain the correct unicode characters represented by this string:

string originalString = "\u0605\u04c3\u5000\u0000\u5000\ufd00\u4400\ud500\u7600\ud300\u4f00\ubc00\u0c00\u2d00\u4000\ue400\u0e00\u7400\u4800\ub700\u1d00\u1300\ue900\u6000\u4c00\ufb00\u9900\u3900\ud900\u6700\uae00\ueb00\u8f00\u2800\u0200\ub300\u5c00\ufe00\u0100\u3d00\u9100\u3000\u0300\u1600\u0100\u7000\u6200\u8e00\u1d00\u8e00\u6200\ua900\u6300\uc800\u0900\ub700\ub000\u6000\ue400\u9200\u3f00\u9100\u8d00\uef00\u3600\u0100\u9e00\u0081";

If I hard-code it in the cs file, I can see in debug mode that it shows the correct characters, but if I have the exact string written in a file and I try to read it, it shows the string as it is in the file.

TextReader tr = new StreamReader("c:\\test.txt");
string tmpString = tr.ReadLine();
tr.Close();

byte[] array = Encoding.Unicode.GetBytes(tmpString );
string finalResult = Encoding.Unicode.GetString(array);

How can I make the finalResult string have the correct unicode characters?

Thanks in advance Gonçalo

EDIT: Already tried placing

TextReader tr = new StreamReader("c:\\test.txt",Encoding.Unicode);

but the characters are different from the correct ones.

Answer 1

Does your file actually contain the content:

\u0605\u04c3\u5000\u0000\u5000\ufd00\u4400\ud500\u7600\ud300\u4f00 \ubc00\u0c00\u2d00\u4000\ue400\u0e00\u7400\u4800\ub700\u1d00\u1300 \ue900\u6000\u4c00\ufb00\u9900\u3900\ud900\u6700\uae00\ueb00\u8f00 \u2800\u0200\ub300\u5c00\ufe00\u0100\u3d00\u9100\u3000\u0300\u1600 \u0100\u7000\u6200\u8e00\u1d00\u8e00\u6200\ua900\u6300\uc800\u0900 \ub700\ub000\u6000\ue400\u9200\u3f00\u9100\u8d00\uef00\u3600\u0100\u9e00\u0081

If so, you need to convert each sequence to its corresponding unicode character

    string originalString = "\u0605\u04c3\u5000\u0000\u5000\ufd00\u4400\ud500\u7600\ud300\u4f00\ubc00\u0c00\u2d00\u4000\ue400\u0e00\u7400\u4800\ub700\u1d00\u1300\ue900\u6000\u4c00\ufb00\u9900\u3900\ud900\u6700\uae00\ueb00\u8f00\u2800\u0200\ub300\u5c00\ufe00\u0100\u3d00\u9100\u3000\u0300\u1600\u0100\u7000\u6200\u8e00\u1d00\u8e00\u6200\ua900\u6300\uc800\u0900\ub700\ub000\u6000\ue400\u9200\u3f00\u9100\u8d00\uef00\u3600\u0100\u9e00\u0081";
    string tmpString = "\\u0605\\u04c3\\u5000\\u0000\\u5000\\ufd00\\u4400\\ud500\\u7600\\ud300\\u4f00\\ubc00\\u0c00\\u2d00\\u4000\\ue400\\u0e00\\u7400\\u4800\\ub700\\u1d00\\u1300\\ue900\\u6000\\u4c00\\ufb00\\u9900\\u3900\\ud900\\u6700\\uae00\\ueb00\\u8f00\\u2800\\u0200\\ub300\\u5c00\\ufe00\\u0100\\u3d00\\u9100\\u3000\\u0300\\u1600\\u0100\\u7000\\u6200\\u8e00\\u1d00\\u8e00\\u6200\\ua900\\u6300\\uc800\\u0900\\ub700\\ub000\\u6000\\ue400\\u9200\\u3f00\\u9100\\u8d00\\uef00\\u3600\\u0100\\u9e00\\u0081";

    string finalResult = Regex.Replace(tmpString, @"\\u(....)", match => ((char)int.Parse(match.Groups[1].Value, System.Globalization.NumberStyles.HexNumber)).ToString());

Answer 2

you can use the Encoding as parameter while reading the file

   TextReader tr = new StreamReader("c:\\test.txt",Encoding.Unicode);
   string unicode_string = tr.ReadLine();

Answer 3

Try something like:

TextReader streamReader = new StreamReader("c:\\test.txt");
string input = streamReader.ReadLine();
string[] chars = input.Split(new char[] { '\\', 'u' }, 
    StringSplitOptions.RemoveEmptyEntries);
streamReader.Close();

string answer = string.Empty;
foreach (string charachter in chars)
{
    byte byte1 = byte.Parse(string.Format("{0}{1}", 
        charachter[0], charachter[1]), NumberStyles.AllowHexSpecifier);
    byte byte2 = byte.Parse(string.Format("{0}{1}", 
        charachter[2], charachter[3]), NumberStyles.AllowHexSpecifier);
    answer += Encoding.Unicode.GetString(new byte[] { byte2, byte1 });
}
