Does the SMSC module support sending emojis?

[Helloworld1668]

Hello buddy !
I have a question, does the SMSC module support sending emojis ? Such as
?
The kamailio project version is 5.3 !
I am currently debugging and can send Chinese and English, but sending emojis causes SMSC to core dump.
Have you encountered a similar issue in your environment? Could you help me solve this problem?

As far as I know, emojis should be working with latest kamailio used in this repo. Not sure about kamailio 5.3 since I havent tested that

[Helloworld1668]

Hello, buddy,
Thank you for your help. The latest SMS code indeed supports emoticons, but I encountered a problem. The SMS module has a character length limit, as shown in the following log prompt. Is there any parameter that can be adjusted?

Hi buddy!
I found the relevant code for smsops and found that the code follows the current standard rules. However, for messages that exceed the current length range, how should we handle them? Can you provide some support for me?

Hi buddy ！
This is the pcap .

I dont think there is any parameter that can be adjusted since SMS concatenation is not supported in kamailio SMSC (https://thesmsworks.co.uk/blog/concatenated-sms/)
