string-limit cannot be used with strings that have wide characters and
characters that are composed on display, if the result is supposed to
be correct on display.  string-limit assumes each character occupies 1
column on display, which is not true in those two cases.  It's the
same problem as with using 'length' when you want to know how many
columns will a string occupy on display.
