What is valid value range for char?
A char supports a 16-bit unicode character and is unsigned 2 byte integer. It can be assigned directly to an integer value but the integer value must be in its value range or you would get a compiler error.
The largest number it can hold is 216 which is 65535. The following value ranges are equivalent to represent the value range of char:
| 0 to 216-1 | dec |
| 0 to 65535 | dec |
| 00 to 0177777 | octal |
| 0x0 to 0xFFFF | hex |
| 0000 0000 0000 0000 to 1111 1111 1111 1111 | binary |
| '\u0000' to '\uFFFF' | unicode |
Any numeric assignment to a char could be cast to a char and get past the compiler in this case the char will only contain the right two bytes.
