Cannot convert gsm to unicode - unicode

Question

Dears
I am using kannel 1.5.0 gateway with smpp on RHEL6 and when I receive an sms I get these errors:
2016-01-28 13:28:07 [8613] [6] WARNING: Could not convert GSM (0xd4) to Unicode.
2016-01-28 13:28:07 [8613] [6] WARNING: Could not convert GSM (0xf2) to Unicode.
.....
and I receive the messages incorrectly to my application, here is the request captured:
http://127.0.0.1:9091/services/smsReceive?msisdn=%2B353872849216&coding=0&smsText=%C3%85%3CH%C3%B9a%C3%91%C3%B9%25evM%C3%B9)zX%C3%ACp&DCS=-1&charset=UTF-8'

I am new to kannel please help if i am doing anything wrong

Answer 1

You should check Kannel docs;
for a "normal" message, it will be "GSM" (coding=0), "binary" (coding=1) or "UTF-16BE" (coding=2)
What I see in url is that
&coding=0
what should be:
&coding=2
and also take care that it is url encoded correctly and about length of unicode message (if you are using aggregators not all support concatenation and long messages)
Hope it helps.
