[tor-dev] non-ASCII handling in tor and onionoo

[nusenu]

Hi,

I'm trying to find out if non-ASCII characters are allowed in descriptor
data (and what onionoo would do with non-ASCII currently displayed as "?").

According to the spec non-ASCII chars are not allowed:
https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n218

I searched trac because I remembered there were some ASCII related tickets:

https://trac.torproject.org/projects/tor/ticket/1258
closed due to
https://trac.torproject.org/projects/tor/ticket/1720 (which has nothing
to do with non-ASCII)
https://trac.torproject.org/projects/tor/ticket/1270


Is this summary correct?

Currently non-ASCII is not compliant with the spec but your consensus is
that non-ASCII chars should be supported but no one got around to patch
the spec and implementation.


thanks,
nusenu

Non-ASCII characters are supported in the contact and platform fields.
Some contact fields use non-ASCII for accented characters, and relay
operators want us to continue to support them.

There is a ticket about requiring ASCII in relay descriptors, which we
should wontfix. There is a ticket about requiring ASCII in extrainfo
descriptors, which we closed because we fixed the underlying
memory disclosure bug.

at least onionoo does not provide any non-ASCII data from ContactInfo
