International characters: Currently we support ASCII + UCS2 characters as well as UTF8.
For encoding, we use GSM-7, unless the message has special characters or emojis. If it has those, we use UCS-2.
GSM-7 can have 160 bytes, with characters represented as 1 byte each (so 160 characters). GSM-7 only supports normal characters.
UCS-2 can have 140 bytes, with characters represented as 2 bytes each (so 70 characters). UCS-2 supports special characters and emojis.
