problem with validation results

I checked my site to validate this page and it says:

Warning: Using windows-1252 instead of the declared encoding iso-8859-1.
http://muralsandfauxpainting.com/faux-painting-glazes.html
Warning: Legacy encoding windows-1252 used. Documents should use UTF-8.
http://muralsandfauxpainting.com/faux-painting-glazes.html
Error: Internal encoding declaration utf-8 disagrees with the actual encoding of the document (windows-1252).
From line 9, column 1; to line 9, column 24 <https://validator.w3.org/nu/?showsource=yes&doc=http%3A%2F%2Fmuralsandfauxpainting.com%2Ffaux-painting-glazes.html#l9c24>
e=1.0" />↩<meta charset="utf-8" />↩<link
But I have saved my file using Smultron to UTF-8. So how come your test says I am using windows-1252?

Can you explain, please. I want to validate my pages.
