If isprint() is called with a fragment of a multibite character,
it just fail.
Thus, it is unnecessary to check whether the current locale is multibyte.

If you prefer to check it, I can fix it easily:


                case 'i':
                        if (!iflag && setlocale(LC_CTYPE, "")!=NULL) {
                                if (MB_CUR_MAX == 1)
                                        iflag = 1;      /* partial i18n mode */
                                else
                                        setlocale(LC_CTYPE, "C");
                        }
                        break;
