Create Zip with utf-8 Filenames (Unicode filenames)

See more Zip Examples

Demonstrates how to create a .zip archive that stores the filenames using the utf-8 character encoding. This allows for filenames of any language to be within a single Zip.

Note: utf-8 is the multibyte encoding for Unicode. When a Zip compression product declares that it supports Unicode filenames, what it really means is that it is capable of reading/writing utf-8. WinZip added support for Unicode (utf-8) filenames starting with version 11.2.

#import <CkoZip.h>

BOOL success = NO;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoZip *zip = [[CkoZip alloc] init];

success = [zip NewZip: @"test.zip"];
if (success != YES) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

// To zip using utf-8 filenames, set the OemCodePage = 65001
zip.OemCodePage = [NSNumber numberWithInt:65001];

BOOL recurse = YES;
success = [zip AppendFiles: @"/temp/NonEnglishFilenames/*" recurse: recurse];

success = [zip WriteZipAndClose];
if (success != YES) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

NSLog(@"%@",@"Zip Created!");
