Support for japanese language in qt in an ARM environment

Hi,
Myself a beginner in qt.I am trying to support japanese font(katakana) in qt using ttf file. I am inputting unicode and getting the japanese font out. I tried giving some unicode /0×30A1 as input(the unicode for katakana letter http://www.charbase.com/images/glyph/12449 ) which is small letter a in katakana.

But what i get was some arbitrary japanese letter to each digit in the unicode…instead of the appropriate single unicode letter.


#include <QtGui>

int main(int argc, char** argv)
{
QApplication app(argc, argv);
QFile fontFile("katakana.ttf");
if (!fontFile.open(QIODevice::ReadOnly)) {
qCritical() << "failed to open font file";
}
QByteArray fontData = fontFile.readAll();

// Register font to the QFontDatabase /
if (QFontDatabase::addApplicationFontFromData(fontDat a) == -1) {
qCritical() << "failed to add a font";
}

// Create font object and verify font family
QFont font3("Katakana", 25, QFont::Bold, true);
QFontInfo fontInfo3(font3);
qDebug() << "Expected:" << font3.family() << "Real:" << fontInfo3.family();

// Produce GUI which uses loaded font

char strarry[22]={'0xE382A1','0xE382A2','0xE382A3','0xE382A4'};
strarry[4]='0xE38385';
strarry[5]='0xE38380';
strarry[6]='0xE382A2';



QLabel label3;
label3.setText(QString::fromUtf8(strarry));

label3.setFont(font3);
label3.show();

return app.exec();
}

what is the correct way to input unicode of katakana ??
Please help…
