Let me share my opinion. I am a Nepali. But when foreigners refered to all people (Nepalis) of nepal .... they probably used the term Nepalese or Nepalis. pachi 'Nepalis' "apabhramsha" bhayera ''Nepalese' bhako huna sakcha. It is same as 'an indian believes' and 'Indians believe' Both should be correct .... and in todays world not every word could be found in the dictionary.
