Here is the current code:

	ret = 0;

	for (i=0; i<wargc; i++) {
		if ((utf8argv[i] = utf8_from_wchar(wargv[i])) == NULL) {
			ret = 1;
			break;
		}
		if (ret != 0) break;
	}

I cannot see how the second break can happen.
If utf8argv[i] != NULL then ret == 0; if utf8argv[i] == NULL then the first
break exits the for(i=...) loop.
