            <div style="font-family: Raleway;">The approach differs not
              only by script and which digits are used, but also by
              language.  Arabic and Persian both use the Arabic script,
              but do things differently when it comes to ordering
              components of a range or expression.<br>

          <p>Isn't that difference handled by having two different sets
            of digits? As opposed to relying on a language tag.<br>

        See the cases in figs. 3 and 4 at <a
          class="moz-txt-link-freetext"
          href="https://r12a.github.io/scripts/arabic/arb.html#expressions"

        Same digits, different expectations about directionality. <br>
        <br>
        I wasn't talking about language tags or behaviour arising from
        character properties (indeed the language tag doesn't make a
        difference) – i was talking about the user expectations
        differing from language to language about the order in which
        digits appear in the text.<br>

    <p>If I understand correctly, this would be a case that's not
      handled by the UBA, then. Would that be worth calling out, you
      think?</p>
