Detailed Description

This is an opaque type for sizes expressed in character units.

Instances of this type represent a quantity as a multiple of the size of the standard C type, char, on the target architecture. As an opaque type, CharUnits protects you from accidentally combining operations on quantities in bit units and character units.

In both C and C++, an object of type 'char', 'signed char', or 'unsigned char' occupies exactly one byte, so 'character unit' and 'byte' refer to the same quantity of storage. However, we use the term 'character unit' rather than 'byte' to avoid an implication that a character unit is exactly 8 bits.

For portability, never assume that a target character is 8 bits wide. Use CharUnit values wherever you calculate sizes, offsets, or alignments in character units.
