XSL-FO Reverted text in footnote

Question

I'm trying to display correctly a footnote inside a PDF with Apache FOP.

<fo:block text-align="right">
    <fo:bidi-override unicode-bidi="embed" direction="rtl">
        <fo:inline>שלום</fo:inline>
        <fo:footnote>
            <fo:inline alignment-baseline="hanging">1</fo:inline>
            <fo:footnote-body>
                <fo:block>
                    <fo:bidi-override unicode-bidi="embed" direction="rtl">
                        <fo:inline>שלום</fo:inline>
                    </fo:bidi-override>
                </fo:block>
            </fo:footnote-body>
        </fo:footnote>
        <fo:inline>.</fo:inline>
    </fo:bidi-override>
</fo:block>

For some reason, the footnote text (at the bottom of the page) appears reverted:

Not sure what I'm doing wrong...

FWIW, I tried your FO with AH Formatter, and the footnote text came out in the reverse order from what you show. So it looks like this could be a FOP bug. Also FWIW, the fo:inline in your sample is redundant. — Tony Graham
Thanks! I created an issue. In the meantime, is there a way to mimic the footnote without using XSL-FO <footnote>? Like having the text appear in the footer? — manash

(bad) Solution approach: remove (the inner) direction="rtl" attribute, but this will probably "break other things".
(better) approach (but maybe not readable/funny in your language, sry, when):
```
<fo:inline>םולש</fo:inline>
```

..but most confusion (for me & maybe "the engine") raise the nested <fo:bidi-override/> elements...

approach 'd be:

<fo:block text-align="right">
  <fo:bidi-override unicode-bidi="embed" direction="rtl">
    <fo:inline>שלום</fo:inline>
  </fo:bidi-override>
  <fo:footnote>
    <fo:inline alignment-baseline="hanging">1</fo:inline>
    <fo:footnote-body>
      <fo:block>
        <fo:bidi-override unicode-bidi="embed" direction="rtl">
          <fo:inline>שלום</fo:inline>
        </fo:bidi-override>
      </fo:block>
    </fo:footnote-body>
  </fo:footnote>
  <fo:inline>.</fo:inline>
</fo:block>

(re-arrange the outer <fo:bidi-override/>.)
