Note that FontConfig configuration files are actually XML files with
extension .conf. Did you look inside all these files?
And there are likely other examples of hidden XML files (not related
to FC) without the .xml extension.
That's why I suggested the commands:

    $ grep -ir 'encoding="utf8' /etc

That will look recursively for any file with the suspicious text.
