Discussion of [NSString NSNonLossyASCIIStringEncoding]

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 NSNonLossyASCIIStringEncoding]

NSData *responseData = ....;

NSString* responseString = [[NSString alloc] initWithData:responseData encoding:NSNonLossyASCIIStringEncoding];

Example of [NSString NSNonLossyASCIIStringEncoding]

NSData *data1 = [myStringTosend dataUsingEncoding:NSNonLossyASCIIStringEncoding];
NSString *goodValue = [[[NSString alloc] initWithData:data1 encoding:NSUTF8StringEncoding] autorelease];

Example of [NSString NSNonLossyASCIIStringEncoding]

1. convert Emoji to unicode

   NSData *data = [strEmo dataUsingEncoding: NSNonLossyASCIIStringEncoding]; NSString *goodValue = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

2. Very easy to convert unicode to Emoji

   NSData *data = [strEmo dataUsingEncoding:NSUTF8StringEncoding]; NSString *goodValue = [[NSString alloc] initWithData:data encoding: NSNonLossyASCIIStringEncoding];
