- A Unicode code unit is a 16-bit char value. For example, imagine a String that contains the letters "abc" followed by the Deseret LONG I, which is represented with two char values. That string contains four characters, four code points, but five code units.
- Chars can be considered as integers if need be without an explicit cast.
- Then since each char occupies one byte, these four bytes represent the three letters 'B', 'y', 'e', and the null character NUL.
- Thus string variables are pointer variables to chars .
- .NET uses the Unicode character set in which each char constant or variable takes up two bytes (16 bits) of storage.
