+1  Q: 

Inserting "£" in a string to a text file

iPhone Application writes data to a text file, saves it on the Documnets folder. Great that works

If I place "£" in the string, or use [currencyStyle stringFromNumber] the text file will not be created.

The "£" and the [currencyStyle stringFromNumber] works if the information is printed to a "New View" page on the simulator, pound and all

Can someone please explain what's happening?

Make sure you're writing your string to the text file with the proper encoding. If you use the -writeToFile:atomically:encoding:error: method of NSString, you should pass NSUTF8Encoding as the encoding argument. You should not use the deprecated -writeToFile:atomically: method.

//make a file name to write the data to using the documents directory: NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt", documentsDirectory]; NSString *content = [NSString stringWithFormat: //save content to the documents directory [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];

I have since used NSUTF8Encoding and can now print the £,but it now has a symbol + the £. any ideas how to get rid of that symbol. Thanks for your suggestion
