[EP-tech] Re: Base64 decoding in 3.3
I have sent you the files. I have also been able to fix it I changed within File.pm I have changes "sub characters" FROM:
print $tmpfile MIME::Base64::decode_base64( substr($_,0,length($_) - length($_)%77) );
print $tmpfile MIME::Base64::decode_base64( substr($_,0,length($_) - length($_)%4) );
this seem to stop the chunking from breaking up?individual?byes and causing the problem. I am still testing this but would be great to know what you think.

I can't replicate this. I did find a bug in XMLFiles for *producing*
base64 encoded files, fixed by this:
This could be an edge case - can you post your XML somewhere or email it
to me directly (if not too big)?
All the best,
