Why does Twitter say my status update is over 140 characters when I only posted 130?

I could tweet hundreds of times on iOS, but I came across one tweet that I just can't tweet. This tweet is only 130 characters long, but Twitter responds by claiming it is over 140 characters long. So Twitter won't post it.

Relevant code:

- (void)tweet:(NSString *)message
    SLRequest* request = [SLRequest
        URL:[NSURL URLWithString:[NSString stringWithFormat:
            @"status": message
    request.account = self.context.account;
    [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *eror) {
        if (responseData != nil) {
            NSLog(@"%@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);


Console printouts:

(lldb) po message
@juandoming Dallas teachers improved student performance by 20% w/mobile video messaging. Would this be useful to you? Ccccccc.com

(lldb) p message.length
(unsigned int) $1 = 130
2014-09-11 12:25:01.326 app[1685:6b13] {"errors":[{"code":186,"message":"Status is over 140 characters."}]}


The actual URL is not Ccccccc.com but has the same number of characters.

Your url is probably 20 characters long.


"For all intents and purposes, all URLs and most things that look like URLs essentially have to be considered 20 characters long when composing a tweet. Clients and sites that display t.co links make this process transparent - see the submission the original bit.ly link is in the UI, but underneath is still wrapped in t.co. "
