![]() UTF-8 is a Unicode encoding that represents each code point as a sequence of one to four bytes. Decoding is the process of transforming a sequence of encoded bytes into a set of Unicode characters. ' This Unicode string has 2 characters outside the ASCII range:Įncoding is the process of transforming a set of Unicode characters into a sequence of bytes. ' The example displays the following output: ' Open the file as a binary file and decode the bytes back to a string.įs = new FileStream(".\UTF8Encoding.txt", FileMode.Open)ĭim decodedString As String = utf8.GetString(bytes) String^ unicodeString = L"This Unicode string has 2 characters " +Īrray^ encodedBytes = utf8->GetBytes(unicodeString ) Ĭonsole::Write( " bytes to the file.", fs.Length)ĭim sr As New StreamReader(".\UTF8Encoding.txt")Ĭonsole.WriteLine("String read using StreamReader:") A Unicode string with two characters outside an 8-bit code range. When the encoded byte array is decoded back to a string, the Pi and Sigma characters are still present. The Unicode string includes two characters, Pi (U+03A0) and Sigma (U+03A3), that are outside the ASCII character range. The following example uses a UTF8Encoding object to encode a string of Unicode characters and store them in a byte array. ![]() SerializableAttribute ComVisibleAttribute Examples
