Description:
[1]
Twitter accept a tweet in 140 characters or below.
Extension:TweetANew has a process to truncate max 140 bytes as a tweet.
But TweetANew truncate a tweet too shorten on some languages (such as Japanese or Chinese) which have multibyte characher.
Because it is using PHP string class which process string as bytes array.
I rewrite it with PHP mbstring class which process string by character.

Now Twitter wrap up all URLs in "t.co", and changed length from 20 to 22 (on https, 21 to 23) characters.
