No. On a German keyboard it gives {. Alt-shift-9 produces á, but the  
bullet is alt-Ÿ: ¥.

No, this cannot be. Otherwise TeX could not process that file or find  
an error: neither a comment sign nor a valid character.

I would need the eMails, the original one and the returned one to  
find this. I don't think that this translation can take place. The  
original character codes are encoded as base64, having only the seven  
less significant bits used, that these codes can pass without change  
every relay.

There are some exceptions in .plist files. They are mentioned in the  
Console from time to time.

I think they are, otherwise I wouldn't have seen German umlauts as  
two bytes with Ã, for example: Schlüsselbund  ...
