Char Data Type
Holds unsigned 32-bit (4-byte) Unicode character code points in the range 0–4,294,967,295.
Char is short for "character".
- Default value
- When you declare a variable of type Char and leave it uninitialized, its value defaults to the character with a code point of zero (0).
- Char is an unsigned type and thus cannot represent a negative value.
- Char widens to String without any risk of overflow.
- Type characters
- Char has no type character.

Dim letter As Char = `A` Dim backtick As Char = ```
