Converting from a Local Encoding to UTF-16

To provide a convenient method for translation between character encodings, RWUString works directly with character-encoding converters in the Internationalization Module.

For example, if you want to write out to UTF-16 a string encoded in the Japanese Shift-JIS, you would use the following.

#include "rw/i18n/RWUToUnicodeConverter.h" // 1

RWCString myString;

// Initialize myString with characters encoded in Shift-JIS

RWUToUnicodeConverter fromShiftJis("Shift-JIS"); // 2

RWByteOutputStream& tmpBStream =

RWByteToStreambufOutputStreamImp::make(cout.rdbuf());

RWDataOutputStream tmpDStream =

RWNativeDataToByteOutputStreamImp::make(tmpBStream);

RWObjectOutputStream out =

RWCompactObjectOutputStreamImp::make(tmpDStream); // 3

out << RWUString(myString, fromShiftJis); // 4

//1 Include the header file for the “to Unicode” converter class.

//2 Create a converter for converting from Shift-JIS to UTF-16.

//3 Create the compact object output stream.

//4 Using the constructor that takes a second “converter” parameter, construct an RWUString from the RWCString containing characters encoded in Shift-JIS. The Shift-JIS characters will be converted to UTF-16 as part of the construction. Then shift out the RWUString.
