ASCII <-> Unicode(CLI)

A sample code from msdn(Unicode to ASCII)

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 array.
array<Byte>^unicodeBytes = unicode->GetBytes( unicodeString );

// Perform the conversion from one encoding to the other.
array<Byte>^asciiBytes = Encoding::Convert( unicode, ascii, unicodeBytes );

// Convert the new Byte into[] a char and[] then into a string.
array<Char>^asciiChars = gcnew array<Char>(ascii->GetCharCount( asciiBytes, 0, asciiBytes->Length ));
ascii->GetChars( asciiBytes, 0, asciiBytes->Length, asciiChars, 0 );
String^ asciiString = gcnew String( asciiChars );

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