Very late reply, but to clarify, what I meant was not 'was is the size of a string' but 'what is sizeof(char)'. Meaning, if your char is a fixed size it can't represent all characters or is wasteful in 95% of all cases (8, 16 or 32 bit) or if it's variable length the formal complexity goes up for a number of often-used operations.
