National characters in SMS on Arduino MKR GSM 1400

Hi forum,

I am using the Arduino MKR GSM 1440 to receive and send text massages. I just can't get national characters (like the åäöÅÄÖ we have in the swedish language) to work. I thought I would need to make conversions between unicode and the GSM 03.38 character set, which is ok, but I don't even seem to get the national characters, when i read them from the incoming message, using client.peek() or

For instance, if i send the text message "abcåäödef" to the Arduino, the string i get will be "abcdef".

Would be grateful if someone could help me on this one.

Also, I am a newbie on Arduino and this is my first post to the forum, so I hope it is ok.

Have you found the way to get national characters ?

So far I have been trying but no way, only ASCII are OK.
