Character counter for SMS Messages

Usage

use Instasent\SMSCounter\SMSCounter;

$smsCounter = new SMSCounter();
$smsCounter->count('some-string-to-be-counted');
$smsCounter->countWithShiftTables('some-string-to-be-counted');

which returns

stdClass Object
(
[encoding] => GSM_7BIT
[length] => 25
[per_message] => 160
[remaining] => 135
[messages] => 1
)
UTF16 notice

When using unicode chars over U+10000 (mainly emoticons 😎) on messages larger than 70 chars the remaining value will actually be the remaining chars in last message part only, this is due to how those chars are encoded using two 16bit chars and max part length being an odd number (67)

Sanitization

You can sanitize your text to be a valid strict GSM 03.38 charset

use Instasent\SMSCounter\SMSCounter;

$smsCounter = new SMSCounter();
$smsCounter->sanitizeToGSM('dadáó'); //return dadao

National Language Shift Tables

Starting release 8 of GSM 03.38 some additional charsets are allowed. This is the list of such National Language Shift Tables currently supported
