Usenet Explorer

Ive encountered this kind of error for the first time, didnt bother me.. meaning i downloaded OK but im curious..
Tried to google it. No results=)
What does it mean exactly? I ve never seen it (and on this file) in nbpro or newsleechers logs
I would appreciate a detailed explanation if you have spare time=)
thanx in advance

Edit menu->properties->articles->detect yenc errors.

If checked it reports those errors, it means some technical problem with yenc, may be also caused by corrupted posts, e.g. when a line gets trimmed or two broken lines become joined together.

By default the option is unchecked (maybe it was checked at some point may be mentioned in release notes), so it gets everything through, then par2 handles all corruptions.
