  I think that's also true for `encoding != 'UTF-8'`. The simplest solution
  would be to show a warning when loading the extension.
  
    def extsetup(ui):
        if encoding.encoding != 'UTF-8' or encoding._wide:
            ui.warn(_('unsupported encoding or terminal setting\n'))
            return
