Select * from something where field1 = N'literal'

Select * from something where field1 = N'literal'

What exactly is happening when a query is sent using the N in front of
the string to be found?
Under what conditions would someone use the N' in a query?
I have been testing out some chinese text. I set up some fields of
nVarchar, nText and it works with an N. Without the N, it wont work.

N also works with fields of varchar and text for english.

Would this ever cause a problem to a query depending on how the
machines regional settings are set? Why not just put N in all of the

If anyone has some ideas, I would be grateful for any and all
information about the N.
