Re: [GENERAL] encoding confusion

The data in the longblob field might be text, which could be causing the
confusion. For example, when I look at the data in the longblob field, I
see /n for a newline and when I look at the bytea it is 012.

I can only tell you what happened in the client end, in terms of
corruption. I am using the Thunderbord client. When I clicked on a
message, it didn't show the data and when I looked at the headers, it
was just a big mess. I'm guessing that somehow the newlines didn't work
and the headers and message were overlaid on top of each other.
