Perfect example. That indicates that at some point, your data passed through a system using Windows-1252 encoding.

I expect Vimeo used a Linux system to collect your data, and I bet the thing that blasts emails out is ultimately Linux as well. So the Windows-1252 bungle probably happened in a third system in between, maybe a Windows system chosen for its ease of administration by the community managers.

Not that this is relevant to data sanitization (they're just being fuckups here) but it shows how complex this can get.
