Client: automatically detect charset and convert and split sms by charset with overlenght to concat sms

[Dexus]

my idee is that the client should automatically convert the charset (ie UTF-8 with only GSM 03.38 chars) to GSM 03.38 or if need (Unicode with other chars as in GSM 03.38) to USC2 charset.

If the message lenght is longer than 160/70(USC2) than split to messages with 153/63 chars.

with header support like in php-smpp
https://github.com/onlinecity/php-smpp/blob/master/smppclient.class.php#L280

CSMS_8BIT_UDH = 153 chars in concat mode
CSMS_16BIT_TAGS = 152 chars in concat mode
CSMS_PAYLOAD = for me unknown; not possible to test with my partners

some encodings in smpp (5.0)
https://github.com/farhadi/node-smpp/blob/master/lib/defs.js#L227

example like:
apihard@791e1b1

unicode (ucs-2[be] / UTF-16BE) is not direct possible with node... need build a converter with iconv or simlar

[eugenehp]

Here is some snippet for you:

var Iconv  = require('iconv').Iconv;
var toucs = new Iconv('UTF-8', 'UCS-2BE');

and you convert it like so:

message = toucs.convert(message);

Don't forget to install dependencies first:
npm install iconv

There also another library you may want to try:
iconv-lite

I don't think shorty will provide such conversion, it belongs to the shorty consumer scope
