This post worked for me. I used your steps to update blogbaltimore and it worked like a charm. I was surprised by the additional step of searching and replacing ?? with the “space character”. It was needed though. Thanks again.

bobby,

It occurred when I did the update on two of my blog sites. If you didn’t see them all the better, they are obvious everywhere if you have them.

There are so many variable in this process, it could be the hosting company, the version of PHP etc.

When they did appear in both of my conversions the process outlined removed them. Good to know it doesn’t occur in all instances.

I don’t think you will see an example because it is really ugly and anyone that does get them will take the steps to remove them, they are very annoying and have to do with certain characters. Those character might be put in by the browser used to create the content in the first place and have nothing to do with MYSQL itself.

I just ran into an instance where an Apple user was using the Opera browser to write blog posts. It was putting in hundreds of extra apple font formatting code which wasn’t visible till you looked at the post in code view. He switched to FF and the issue was resolved.

Hi Dave,
I did the conversion, and view quite a number of posts. Did not see any aberrant (?). I went ahead and did the search-and-replace anyway.

Just curious where you read/heard about the necessity for this step? Do you know an example post where the problem would occur?

Thanks for good article. Very useful info.

bobby,

As I stated in the post, if you don’t do that step all of your posts will be filled with question marks where there should be space characters in certain situation.

If you do this conversion process you will see them.

What is being accomplished by search-and-replace of ?? with space character?

Is it necessary? If that is not done, what functionality is being messed-up? Thanks.
