Bad sms encoding

[Regela]

I am trying to receive SMS using your program and it usually works correctly. But instead of some messages, it shows bad message. Here is an example:

{"smsc":"10.1.2.11:7777","system_id":"krechet01","system_type":"","source":"PHONE_NUMBER","target":"krechet01","message":"tJM#G.Θ<t¿","deliver_time":"2023-07-13T15:02:52.449030921+03:00"}

I caught this message, I bring it:
