iOS 5.0 Check if NSString contains Emoji characters

I have an iOS 5 application that allows users to enter username with international keyboards. I want to check if the input (NSString *) contains an emoji character or not.

Disabling emoji keyboard is not an option (Using UIKeyboardTypeASCIICapable as it disables some of the international keyboards).

I tried this. But it does not detect some of the characters like these.

Is there a good way to solve this problem?

To iOS 10 and below, you should check if the unicode if between the following values.

if ((0x1d000 <= uc && uc <= 0x1f77f) || (0x1f900 <= 0x1f9ff)) {
     //is emoji
}

Use https://github.com/woxtu/NSString-RemoveEmoji Category, but note that iOS 9.1 added more emojis that above mentioned method doesnt recognize (especially these ones:🤐🤑🤒🤓🤔🤕🤖🤗🤘🦀🦁🦂🦃🦄🧀).

FIX: replace
return (0x1d000 <= codepoint && codepoint <= 0x1f77f); in isEmoji method with
return (0x1d000 <= codepoint && codepoint <= 0x1f77f) || (0x1F900 <= codepoint && codepoint <=0x1f9ff);

NSData *data = [yourstringofemo dataUsingEncoding:NSNonLossyASCIIStringEncoding];

NSString *goodValue = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];


if ([goodValue rangeOfString:@"\u"].location == NSNotFound) 
{
      goodvalue string contains emoji characters
} 
else
{
      goodvalue string does not contain emoji characters
}
