Don't include the byte reserved for the nul in the outleft size.
2002-10-16 Jeffrey Stedfast <fejj@ximian.com> * gal/widgets/e-unicode.c (e_utf8_from_gtk_string_sized): Don't include the byte reserved for the nul in the outleft size. (e_utf8_from_iconv_string_sized): Same. (e_utf8_to_iconv_string_sized): Here too, but also make sure we pad the end of the resulting string with enough nul bytes (4) so that even multi-byte charsets are terminated correctly. (e_utf8_to_gtk_string_sized): Again here. svn path=/trunk/; revision=18377
