## Summary This adds character counter below the “Send” button in SMS conversation. It uses format XXX/Y where XXX is number of characters that can be added without splitting the SMS into multiple messages (see article Concatenated SMS on Wikipedia). Y is number of messages in in current concatenated SMS. The counter is not visible when insertion of 10 7-bit or 16-bit (depends on SMS encoding) does not create concatenated SMS. SMS encoding is automatically guessed. 8-bit encodings are not supported. If the message contains characters that are not supported by GSM 7-bit encoding, counter automatically switches to UCS-2. ## Test Plan Try entering some text that is longer than 150 characters in [GSM 03.38 encoding][1] or 60 characters in UCS-2. Number of remaining characters should be visible below the “Send” button. The character counter should show `0` at exactly 160 or 70 characters. Inserting one character should switch the counter to [Concatenated SMS][2] mode when number of messages is shown. It should show exactly same number as SMS app in Android. ## Screenshots These images are in APNG.
