 Almost all of the "Could not parse" warnings on the CollecTor mirror are
 caused by [https://onionoo.torproject.org/details?search=swetor
 SweTor247].

 It seems that some of the country codes use non-ascii characters. The code
 parsing this information is
 [https://gitweb.torproject.org/collector.git/tree/src/main/java/org/torproject/collector/relaydescs/RelayDescriptorParser.java#n272
 here].

 Shouldn't the parser just replace the problematic characters by a default
 character and thus keep the readable information?

 I'll add a stack trace when this happens again.
