Hello,
I'm using kannel in a production environment with several smsc's. (some
smpp 3.4, some emi connections).
Encoding for special characters works for all smsc's except one telco
that is connected via smpp3.4 however;
Stuff like é è ï à is not received ok when we use conversion to utf-8
We have our application recode special chars (which are avilable in
GSM-ASCII, and the ones you list below look like they are) to GSM-ASCII
and send them with default encoding. This is usually supported by most
smpp smsc's, although we have had the occasional problem when the smsc
we send to was
