Google Transliteration offers an option for converting English characters to the characters used in Nepali. This lets you type Nepali words phonetically in English script and then have them appear in Nepali. Note that this is not the same as translation – it is the sound of the words that are converted from one alphabet to the other, not their meaning. For example, typing “Deepak” transliterates into Nepali as दीपक .
