What’s the easiest way to make KrutiDev text readable everywhere?

I’ve been facing a strange issue while working with Hindi typing content. The text looks perfectly fine on my computer, but whenever I paste it into a website, email, or mobile app, it turns into unreadable characters.

After searching around, I found out that the problem is related to older Hindi fonts like KrutiDev not being Unicode-based. Apparently, the text only displays correctly if the same font is installed on the other device, which makes sharing content pretty difficult nowadays.

A few people recommended converting the text from krutidev to unicode before publishing or sharing it online. From what I understand, Unicode text works across all devices and browsers without requiring any special font installation.

Has anyone here tried this method?
