Sanskrit Text Appears Garbled in InDesign – Font Conversion Issues

I am working on an article that includes Sanskrit text. I have tried two different Adobe Sanskrit fonts (Two Devanagari Sanskrit and Tiro Devangari Sanskrit). I have flowed the text from Word and converted the fonts. I have copied the text from a Plain Text document , pasted it in place, and converted the fonts. According to the widow of the author, in all these cases, the text becomes garbled and unreadable. Must I use a Unicode font instead? Why aren't the Adobe fonts simply converting the characters as they should?

I hope others have had and solved this problem.
