Wiimote pairing?
Sorry for the lack of proper thread headers. I subscribed to ask about this very issue and it turns out it was asked two days ago in the already, after I checked out the archives :)
Seeing as everything is done using strings everywhere, including the storage (which is a text file), I think it might be easier to just define a hex format. Something like $0011deadbeef for raw binary pincodes expressed as hex. This will let all the existing tools handle a raw PIN.
The Bluetooth spec talks about numeric and alphanumeric PIN codes, but I haven't seen mention of special characters. I think the likelihood of having issues with real PINs with a starting $ sign is fairly low (and they could always be expressed as hex).
An alternative would be to use a more traditional backslash escape sequence type format, but that's harder to parse.
