Discussion of [NSString NSWindowsCP1251StringEncoding]

These values represent the various character encodings supported by the NSStringclasses. This is an incomplete list. Additional encodings are defined in String Programming Guide for Core Foundation (see CFStringEncodingExt.h); these encodings can be used with NSString by first passing the Core Foundation encoding to the CFStringConvertEncodingToNSStringEncoding function.

Example of [NSString NSWindowsCP1251StringEncoding]

NSString *myStr = [[[NSString alloc] initWithData:[response responseData] encoding:NSWindowsCP1251StringEncoding] autorelease];
    myStr = [myStr stringByReplacingOccurrencesOfString:@"encoding=\"windows-1251\"" withString:@""];
    myStr = [myStr stringByReplacingOccurrencesOfString:@"US-ASCII" withString:@"UTF-8"];
    NSData* aData = [myStr dataUsingEncoding:NSASCIIStringEncoding];

    rssParser = [[NSXMLParser alloc] initWithData:aData];
    [rssParser setDelegate:self];
    [rssParser setShouldProcessNamespaces:NO];
    [rssParser setShouldReportNamespacePrefixes:NO];
    [rssParser setShouldResolveExternalEntities:NO];

    [rssParser parse];

Example of [NSString NSWindowsCP1251StringEncoding]

// Convert it back to CP1251
NSData *dt = [mystr dataUsingEncoding:NSWindowsCP1251StringEncoding];

// Now load it as UTF8
NSString *str = [NSString alloc] initWithData:dt encoding:NSUTF8StringEncoding];

Example of [NSString NSWindowsCP1251StringEncoding]

NSString *textRev=[[NSString alloc]initWithData:data encoding:NSWindowsCP1251StringEncoding];

 NSLog(@" Actual String.. %@",textRev);
