Comment (by teor):

 For the record, prop285 has tor switching to UTF-8 for all documents that
 used to be ASCII.

 Currently, this affects platform/version and contact lines.

 The spec requires ASCII for the other descriptor, vote, and consensus
 lines, and all other documents. But since tor doesn't parse ignored fields
 and lines, and doesn't always enforce ASCII, there will continue to be
 some parts of these documents that allow UTF-8.
