agree'ing here fully with Andreas....
BTW, we had this discuission off-list for a SMPP SMSC in India that exptexts
7bit GSM alphabet packed in 8bit bytes for concat messages, but not for non-concat.
So, according to SMPP v3.4 spec, (this is the generic interpreation from anyone
who claims to have "knowledge", not me ;) GSM chars are simply passed into a
single byte and have not to be packet.
