Add feature for GSM Character Set (UTF-7, UTF-8, UCS) SMS Gateway
Suggestion: Add feature to define what GSM character to define in SMS Gateway, is neccesary limit the long size based on the character set encoded to use 7-bits for 140, 8-bits for 160 characters. Also, UCS-2 messaging which allows sending most unicode characters, but as each of these takes 2 bytes it means only 70 characters can be sent per 1 SMS. This feature is important to define the cost for messages depending the encoded used.
This functionality is available in v5.0. You will be able to see which encoding it uses. You can download it from CodeCanyon. Please rate the SMS Gateway on CodeCanyon. It will help me a lot.
