Problem with compressing unicode file names in zip file

Question

Hi Everyone,
I have a problem while compressing the unicode file name in a zip file. I used the below code for compressing the unicode files.
String[] source = null;
// C:\\TestData\\unicode_filename.txt :  unicode_filename.txt is the file created in japanesse language
source = new String[] {"C:\\TestData\\temp_properties.xml","C:\\TestData\\unicode_filename.txt" };
byte[] buf = new byte[1024];
// Create the ZIP file
String target = "C:\\TestData\\target.zip";
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(target));
// Compress the files
for (int i = 0; i < source.length; i++)
     FileInputStream in = new FileInputStream(source);
     // Add ZIP entry to output stream.
     String fileName;
     File tempFile;
     ZipEntry zipEntry = new ZipEntry(source[i]);
     fileName = zipEntry.getName();
zipEntry = new ZipEntry(fileName);
zipEntry.setMethod(ZipEntry.DEFLATED);
getUTF8Bytes(source[i]);
// here I'm unable to find the unicode files and not able to understand.
out.putNextEntry(zipEntry);
// Transfer bytes from the file to the ZIP file
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
// Complete the entry
out.closeEntry();
in.close();
// Complete the ZIP file
out.close();Please help me how to fix this issue.
