How to escape string characters on sms notification?

I'm sending SMS notifications including address as such: $position.address , the problem is that I'm getting the messages with wrong characters or unescaped strings like "Ignition ON at: 199 León López Sanabria", is there a function inside the template engine to escape the characters á é í ó ú ?

Thanks in advance and thanks for the great work on traccar :)

What SMS provider are you using?

Hello, I'm using the traccar SMS Gateway official app, greetings!

Hello Anton, I've narrowed the problem to the SMS Gateway app because I got the same error with curl:

curl --location --request POST 'http://192.168.1.78:8082/' \
--header 'Authorization: 8a326fb0' \
--header 'Content-Type: text/plain' \
--data-raw '{
        "to": "+523327847531",
        "message": "Hola á é í ó ú"
    }'

And still weird characters. Any help would be appreciated!

It might not be supported.

Ok, Anton, I may try to proxy the requests and remove the special characters then. Thanks a lot for the help and the great work with Traccar!
