Punjabi In Photoshop Not Working

Hi everyone!

So I am doing a job where I to put different messages into a video in many different languages. To make the messages I am using photoshop and putting text onto a background. English is working fine. When I try to use punjabi, it uses a punjabi font but it doesn't say what it is supposed to say and the accents on the words are wrong and pretty much the whole thing is just not right. I do not speak punjabi so this is a big challenge. Hopefully someone can help me!

Thanks!
