Please do not reopen this discussion again:

UTF-8 gives rise to multiple measures of 'length'. So you need
multiple operators or functions anyway. The most appropriate
choice for #s is the definition which is common to all strings.
And this is the length in bytes. No need to override this.

BTW: The length in characters is mostly meaningless for UTF-8.
     You probably want glyphs or screen real-estate.

Bye,
