If you look through my previous posts you will notice a lot of extraneous characters scattered about haphazardly. This happened after my website was hacked. I first thought it might be a further hack but it turns out it is a result of my site having been moved to a newer server, with theoretically greater security, after the hack was corrected. I think it is a problem with the character set on the old server databases vs. the new one.
I will be looking into fixing the problem if it continues, but if it disappears from now on I will probably just ignore the old posts. They are readable.
