And in 99% of the cases, using length-bytes doesn't do what you think
(it doesn't count the number of bytes that it would take in your
favorite coding-system, but the number of bytes it takes within Emacs's
internal encoding).
If you want to know how many bytes it would take in your locale's
encoding, then you need:
(length (encode-coding-string <thestring> locale-coding-system))
