将 Unicode 字符串转换为正确的字符串

Question

我有一个包含 unicode 数据的字符串。

我想把它写在一个文件中。当数据写入文件时，它给了我简单的 unicode 值而不是英语以外的语言。

string originalString = ((char)(buffer[index])).ToString();
//sb.Append(DecodeEncodedNonAsciiCharacters(originalString.ToString()));
foreach (char c1 in originalString)
{
    // test if char is ascii, otherwise convert to Unicode Code Point
    int cint = Convert.ToInt32(c1);
    if (cint <= 127 && cint >= 0)
        asAscii.Append(c1.ToString());
    else
    {
        //String s = Char.ConvertFromUtf32(cint);
        asAscii.Append(String.Format("\\u{0:x4} ", cint).Trim());
       // asAscii.Append(s);
    }
}

sb.Append((asAscii));
Console.WriteLine();

当我看到输出文件时，数据显示如下

1 00:00:27,709-->00:00:32,959 1.2 \u00e0\u00a4\u0085\u00e0\u00a4\u00b0\u00e0\u00a4\u00ac \u00e0\u00a4\u00b2\u00e0\u00a5\u008b\u00e0\u00a4\u0097 28 \u00e0\u00a4\u00b0\u00e0\u00a4\u00be\u00e0\u00a4\u009c\u00e0\u00a5\u008d\u00e0\u00a4\u00af \u00e0\u00a4\u0094\u00e0\u00a4\u00b0 \u00e0\u00a4\u00b8\u00e0\u00a4\u00be\u00e0\u00a4\u00a4 \u00e0\u00a4\u0095\u00e0\u00a5\u0087\u00e0\u00a4\u0082\u00e0\u00a4\u00a6\u00e0\u00a5\u008d\u00e0\u00a4\u00b0 \u00e0\u00a4\u00b6\u00e0\u00a4\u00be\u00e0\u00a4\u00b8\u00e0\u00a4\u00bf\u00e0\u00a4\u00a4 \u00e0\u00a4\u00aa\u00e0\u00a5\u008d\u00e0\u00a4\u00b0\u00e0\u00a4\u00a6\u00e0\u00a5\u0087\u00e0\u00a4\u00b6

但它应该看起来像这样

1 00:00:27,400 --> 00:00:32,760 1.2 अरब लोग 28 राज्य और सात केंद्र शासित प्रदेश

我尝试了很多事情，但都没有完成我的工作。

Answer 1

string unicodeString = "This string contains the unicode character Pi(\u03a0)";

     // Create two different encodings.
     Encoding ascii = Encoding.ASCII;
     Encoding unicode = Encoding.Unicode;

     // Convert the string into a byte[].
     byte[] unicodeBytes = unicode.GetBytes(unicodeString);

     // Perform the conversion from one encoding to the other.
     byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);

     // Convert the new byte[] into a char[] and then into a string.
     // This is a slightly different approach to converting to illustrate
     // the use of GetCharCount/GetChars.
     char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
     ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
     string asciiString = new string(asciiChars);

     // Display the strings created before and after the conversion.
     Console.WriteLine("Original string: {0}", unicodeString);
     Console.WriteLine("Ascii converted string: {0}", asciiString);
