hi vinod,
I got the solution.
I just change the CHARACTER_SET format to UTF-8 while encoding and works without culture setting.

Hi vinod,
I got one image from client which is encoded in Japanies. while decoding it am getting this error
"An unhandled exception of type 'com.google.zxing.ReaderException' occurred in zxing.dll" in Detector class Line number 218. Any suggestion ?

Hi Vivek,
While decoding also you have to specify the hint.

Solution 2

Hashtable hints = new Hashtable ();
                        hints.Add(EncodeHintType.CHARACTER_SET, "UTF-8");
// Encode function is having Japanese characters as input 
            ByteMatrix byteIMG = qrCode.encode("親愛なる歓迎$#@25", BarcodeFormat.QR_CODE, 120, 120, hints);

Hi Vivek,
EncodeHintType.CHARACTER_SET is there but there is no DecodeHintType.CHARACTER_SET in that DLL that why its showing error.In that url there is another dll which having that option.

The actual error is
'UTF8' is not a supported encoding name.
Parameter name: name

Need your help once again.
I have created zxing related question here.http://www.codeproject.com/Questions/448193/zxing-winrt-library-WriteableBitmap-does-not-conta

Please guide me..

Hi Vinod,
This error I got while encoding, so for this I have passed encoding parameter and it resolved.this as
Hashtable hints = new Hashtable ();
hints.Add(EncodeHintType.CHARACTER_SET, "UTF-8");
It decoded also well. but the images I received from client giving error as above while decoding.
