Hello! Sorry for the delayed response.
Here's how it looks pasting the headline from that article into STM, it does look like there's a difference:
...So unfortunately, it doesn't look like it works out of the box. I'm trying to look for a third-party script that would adjust the text for rendering in Unity, but for some reason they either require specific fonts to be used, or are things people don't want to share online. But I know it's got to be possible... If you can find a script that adjusts the text and it works with what Unity has built-in, it will work with STM. But from my inexperience with Indian languages, I don't think I can write this kind of script myself. (Like how I didn't write the bulk of the Arabic language support, just the part that connects it to STM)
