I don't think so - the spec for %n says 'stores the number of
characters written', when what we want is the width in columns
of the string.
wcswidth(mbstowcs(str)) is the number really wanted -- except that we
can't count on those functions being present, and even if we could, we
can't count on str being in the character set mbstowcs expects.
