What is this i dont even

Twitter’s “Oops! Your update was over 140 characters. We sent the…” message flashes away from view way too fast; the afore quoted part was all I could read before it vanished. Also, as the real-time character counter indicated (‘0’ left), my tweet was exactly 140 characters long. Apparently this has to do with Twitter using ASCII to encode accented characters. What a nice excuse for a usability FAIL.
