As far as I can see, printf is not calculating strings lengths

printf(1) explicitly states that it works with ASCII and ANSI
X3.159-1989 (``ANSI C89'') character escapes, and it also notes:
Multibyte characters are not recognized in format strings (this is
only a
problem if `%' can appear inside a multibyte character).
Some platforms have a printf_l(3) which is locale/xlocale-aware, but
there doesn't seem to be a corresponding CLI utility which understands
Unicode/UTF8/widechars.
Thanks for your explanation.
Do you have a suggestion to solve the following problem without using
printf(1):
I have a text file that I want to print in a "box" on a terminal from a
shell script. Now I've padded the lines with spaces to a certain length
using printf %-70s and appended the box drawing character. Is there
another simple way that will work with utf-8?
