Important Comments on Decoding YEnc Files
yEnc is different from the usual encoding methods in that it uses non-
ASCII characters in the encoded text. Therefore to properly download
such attachments prior to decoding, the downloading program has to
make sure that it does not strip out control characters or convert
8-bit characters or modify the attachment text in any way. This will
rule out using many programs to download
yEnc posts before decoding as they will modify the text being
downloaded and therefore corrupt it.
Rosetta can properly decode yEnc files only if they have not been
corrupted during downloading. Because Rosetta is primarily designed as
a decoder for usenet binary attachments, where various forms of
corruption may occur for a variety of reasons, the program does its
best to recover as much of the original file as possible without
reporting errors or refusing to decode imperfect files. Normally this
is an advantage, as attachments may be incomplete or have a bad line
of text and still yield a useful file. But in the case of a yEnc
attachment downloaded with a program that corrupts yEnc posts, a
corrupted yEnc attachment will probably not yield a useful file.
There are 4 different things that original NewsWatcher does when
fetching an article and downloading it to disk that cause yEnc
corruption. MT-NewsWatcher 3.1 and earlier versions can not download
yEnc attachments using the normal Save or Extract Binaries commands
without causing corruption, and the same is true of YA-NewsWatcher.
MT-NewsWatcher 3.2 can be successfully used to download yEnc binaries
to be decoded by Rosetta.
As noted, yEnc is different in significant ways from older encoding
methods. Older newsreaders that were not designed with yEnc in mind
may well do things that are proper in the context of the time when
they were written but which prevent yEnc from working. Some of these
programs may have a feature that permits articles to be exported in
source or raw or mailbox format. yEnc files saved in this manner may
be free from corruption and therefore decode properly using Rosetta.
