The way to go here is via `RawInline` elements, e.g.:

    function Str (s)
      if s.text == '–' then
        return pandoc.RawInline(
          'html',
          '<i class="material-icons">face</i>'
        )
      end
    end

Note matching on an exact string would fail if the character was
somewhere within a word (a typical would be em-dashes). One would have
to use the [utf8.codes] module to manually find and replace those
characters in that case.
