I need to create a MS WORD document in Nepali. I can type in Neapli at Google Transliteration. But when I copy it to MS word, all i see is square boxes. Can some one please help me out? I really appreciate it.

 you need to install nepali fonts if you want to type in Nepali.
here is the link: http://www.nepali.info/nepali/fonts/ read how to install at the bottom of the page.

 install Nepali unicode from http://www.madanpuraskar.org/downloads.php i have been using the same, It works in win xp vista n win 7 best of luck

you wont be able to open the document in other computer if you write through nepali unicode so it will be better if you write those by insalling nepali font in your computer..

For that I suggest you use Nepali Unicode! There's option to convert Nepali Unicode to Preeti Unicode too! Hope there will be no problem when using Nepali Unicode
