It looks like the string returned for '3814' is just different in this case, see: https://testbot.winehq.org/JobDetails.pl?Key=128382#k113
What's even stranger is that the unicode version sometimes doesn't match with ansi version, see: https://testbot.winehq.org/JobDetails.pl?Key=128384#k115
I think it's probably best to just remove the test for this code. Bonus points for cleaning things up a bit too.
