The key difference between varchar and nvarchar indicates how data are stored in a database. â¢ Varchar stores ASCII values and nvarchar stores Unicode characters. â¢ Varchar uses one byte per character while nvarchar uses two bytes per character.
The differences are: 1  n[var]char stores unicode while [var]char just stores single-byte characters. [ 2 n]char requires a fixed number of characters of the exact length while [n]varchar accepts a variable number of characters up to and including the defined length.
