Tip 8: Don't confuse Size() and Length().
Size() returns the number of bytes the descriptor occupies.
Length() returns the number of characters the descriptor contains.
For 8-bit descriptors, where each character occupies a byte, this is the same thing. However, on all releases of Symbian OS since v5u, the native character width has been 16 bits; that is, each character occupies two bytes.
Thus, unless you're working with a very old SDK, you'll find that Size() always returns a value which is double that of Length().
