Summary:                    UTF8 support. Sortfield generated ignoring multibyte
symbols.
Description: 
dm_messages.c:
function _header_cache
.....
        if(issubject) {
                char *s, *t = dm_base_subject(value);
                s = dbmail_iconv_str_to_db(t, charset);
                g_strlcpy(sortfield, s, CACHE_WIDTH-1);
                g_free(s);
                g_free(t);
        }
.....

It does not work correctly with multibyte strings.
