I am using the phone above to send out sms text "ČĎŮčetina", received log smsd.log:

GSM2: <- +CMGR: 0,,43 0791246080006528240C9124707362023800085101521273614018010C0160010E016E011A010D0065016100740069006E0061 OK
GSM2: SMS received, From: 420xxxxxx
GSM2: Wrote an incoming message file: /var/spool/sms/incoming/GSM2.eWX423

view on the file /var/spool/sms/incoming/GSM2.eWX423 :

Subject: GSM2
Modem: GSM2
IMSI: 230030090959675
Report: yes
Alphabet: UCS2
Length: 12
PDU: 0791246080006528240C9124707362023800085101522260024018010C0160010E016E011A010D0065016100740069006E0061


Why PDU decoder text is too poor to convert the text into shape?
Has a problem with Alphabet: UCS2 (16) bit?

Message body in the file is UCS2 coded. You can use the eventhandler to convert this kind of incoming messages to UTF-8. In global part of smsd.conf, define:
eventhandler = /usr/local/bin/

Create this file with a following content:


if [ "$1" == "RECEIVED" ]; then

  if sed -e '/^$/ q' < "$2" | grep "^Alphabet: UCS2" > /dev/null; then
    TMPFILE=`mktemp /tmp/smsd_XXXXXX`
    sed -e '/^$/ q' < "$2" | sed -e 's/Alphabet: UCS2/Alphabet: UTF-8/g' > $TMPFILE
    sed -e '1,/^$/ d' < "$2" | iconv -f UNICODEBIG -t UTF-8 >> $TMPFILE
    mv $TMPFILE "$2"

'bash' Syntax Highlight powered by GeSHi

Make the file executable for smsd and restart the daemon.

I've changed the code to the following:

This seems to work better with unicode and emojis. With UNICODEBIG incoming messages has been cut at emojis.
