Why is the name of the Microsoft Wireless Notebook Presenter Mouse 8000 hard-coded into the Bluetooth drivers?

Some time ago, people noticed that buried in the Windows Bluetooth drivers is the hard-coded name of the Microsoft Wireless Notebook Presenter Mouse 8000. What’s going on there? Does the Microsoft Wireless Notebook Presenter Mouse 8000 receive favorable treatment from the Microsoft Bluetooth drivers? Is this some sort of collusion?

No, it’s not that.

So, what is the actual problem? It’s a funny one: an encoding mistake. The device local name string for a device needs to be encoded in UTF-8, and that’s where the developers of the Microsoft Wireless Notebook Presenter Mouse 8000 made a mistake. The string contains a registered trademark symbol – ® – but they encoded it in code page 1252, which not only isn’t allowed, but gets rejected completely.

So, Windows’ Bluetooth drivers have a table that contains the wrong name for a driver, accompanied by the right name to use. This mouse is the only entry.
