In essence that is what my initial hack does, though I filtered with
isprint():

static void
print_string(sdp_data_t *data)
{
        char buffer[50];
        sdp_data_t str;
        int n;

        if (!sdp_get_str(data, &str))
                return;

        if (encoding != NULL)
                printf("(%s) ", encoding);

        for (n = 0; n < sizeof(buffer) && str.next + n < str.end; n++)
                buffer[n] = (isprint(str.next[n]) ? str.next[n] : '.');

        printf("\"%.*s\"\n", n, buffer);
}

I was just hoping for something a little more flexible as I suppose that
won't work with japanese for instance?
