The reason why it was working before is that the server was just looking for the first number it could find and ignoring everything else. However this also leads to inaccurate detections in some cases, so now things are a little more strict in 4.8 and it's only looking for certain conventions. And this character: ยช is not in the list of what it's looking for. So we'll get this resolved in 4.8.1. Thanks.
