I was uploading some changes in Web Expression and received the following error.  The error said “Expression Web was unable to determine the encoding of this file.  Please choose an encoding from the list box below”.


I changed the encoding in the file and saved.  But the error message continued.  I couldn’t figure out how to make the change.  I did some Google searches and found others with the same problem.  Unfortunately, their fixes didn’t help.

Finally, I figured out the issue.  The encoding error wasn’t in the file I had opened but was in one of the JavaScript that was linked to the file.
