“Non Unicode character”, like every non-concept, is vague. In plain English means “every character whose identity is not assigned by means of the Unicode tables”.

What are the features of Unicode?

Comparing with other character coding standard, Unicode has the following unique features:Full 16-bit coding. … Big enough to handle all existing written languages and symbols. … Characters in the same language are coded in groups and ordered according their natural sequence whenever it’s possible.No escape sequences.More items…

What is Unicode datatype?

Understanding SQL Data Types : SQL Data Types : Unicode Data Types. Unicode Data Types. Data types nchar, nvarchar, and long nvarchar are used to store Unicode data.
