 Future Tor will not publish non-ASCII descriptors and dir auths will
 reject them at some point.

 Since this is quite far in the future, what do you think about removing
 such strings in onionoo (before it reaches tor)?
 I'm not suggesting to ignore the entire descriptor in such a case but just
 replace such chars with "?" ?
 "??B`?
" -> "??B`??"

 Note: I used "non-printable" (vs. non-ASCII) since onionoo data includes
 printable but non-ASCII chars.
