ios UTF8 encoding from nsstring

Question

I am receiving a nsstring that is not properly encoded like "mystring%201, where must be "mystring 1". How could I replace all characters that could be interpreted as UTF8? I read a lot of posts but not a full solution. Please note that nsstring is already encoded wrong and I am not asking about how to encode char sequence. Thank you.

Solution 1

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding is what you want. basically use it like so:

newString = [myString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Solution 2

[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]

Solution 3

lblDate.text=[NSString stringWithCString:[[arrTripDetail valueForKey:Param_vCurrencySymbol] UTF8String] encoding:NSUTF8StringEncoding];

U can Convert & get Custom Emoji to string

eg :

input : \U20b9

Output: ₹

Solution 4

Check the Strings and Non-ASCII Characters section of Formatting String Objects:

NSString *s = [NSString stringWithUTF8String:"Long \xe2\x80\x94   dash"];

Solution 5

Do you want just percent encoding/decoding or full URL encoding/decoding? -(NSString*)stringByReplacingPercentEscapesUsingEncoding: will work if it is just percent encoding, but if there is full URL encoding there (so, for example a space could be either %20 or +) then you'll need something like the url decoding in the three20 library (or search on there, there are lots of examples of how to do it such as URL decoding/encoding NSString).
