uuencode help

[Dave Cook]

I'm trying to use the uu module to encode binaries that can then be sent to
an nntp server.  However, when I try to decode these posts with slrn, they
fail to decode.  I've noticed that where uu.encode uses a space, the
standard unix uuencode uses back ticks (`), though this may not be the only
difference.

Does anyone know what's going on here?  If the back tick is the only
difference, I suppose I can do a character replacement.

Thanks
