But that what's POSIX requires (and this hasn't changed in the latest
draft). Also, there may be reasons (e.g. file formats with limited
field sizes). So, zsh should follow the specification, at least when
it emulates sh, since the user may write scripts based on it.

Well, there could be an extension to give the sizes in characters
instead of bytes.

There's a missing semi-colon:

printf() { emulate -L zsh; unsetopt multibyte; builtin printf "$@"; }
