The peculiarity is that if the Nepalese I receive is in Excel or even straight text in an email the only font available to me in Illustrator is Adobe Devanagari (in the sample column of the font menu this is in Roman writing)
If I receive the Nepalese in an Illustrator file and the example I have I was sent is using the font Preeti then I can change it to any of the Nepalese fonts I have installed (which in the sample column of the menu is in Sanskrit writing)
Cheers
