Spaces show up as question marks in post summary

I did an initial search but came up with nothing definitive.  Any help is appreciated.

When looking at a summary of my forum list, all the dates are separated by little question marks.  It is like the spaces are not recognized correctly.  How can I clean this up so these characters are removed and the spaces show correctly?  I've linked a screen shot for reference.

This has been going on for several versions now.

Thanks again in advance and thanks for putting out a great product.

To do this log into the admin area and go to the Date/Time settings page, then resubmit the page. This will save the time and date formats in the new page encoding so that you no longer have the issue you describe in your post.

Man, you are the best!  That fixed it.  It has been annoying me for so long.  Thank you so much and thanks for responding so quickly!
