Strange charset conversion for received SMS

[GoogleCodeExporter]

I'm using chan_dongle 1.1.r29 on asterisk 1:1.6.2.9-2+squeeze10 (debian 
squeeze), with an K3765, and works perfectly for audio, but i've still some 
trouble with SMS.

I've configured my cordless phone (a gigaset IP one) to send and receive SMS, 
using asterisk SMS(), and i can send flawlessy SMS to internal phones and (via 
SendSMS()) to external one using the dongle. I've laso tried to use the CLI, 
and on sending part charset are correctly converted and works; a log exerpt 
looks like:

As you can see, the accented char get mangled; i've also tried to send some set 
of GSM alphabet, and tried to compare the receving part, but seems some sort of 
(wrong) charset conversion occur, really i don't understand how.

I'm not a C programmer, but if needed i can do some test.

Thanks.

I'm not a skilled C programmer (really: i can read some C code...), but my 
system is now practically unused, and so i can at least do some test...

Say me if i can be useful in some way... thanks.
