I think this is an issue of fallback fonts in the font-family property. The
entities are resolving, but the font being used does not contain a glyph for
the missing character.
When I run your test file with XEP 4.16, I don't see the problem you are
seeing; all the symbols display properly. When I view your PDF file with
Acrobat Pro and use the Text Touchup Tool to examine the fonts used for
those missing characters, I find the following:
- In footnotes, the cap symbol is rendered with Symbol font.
- In text, the cap symbol is rendered with Cardo font.
And it seems that the Cardo font does not contain the cap character.
Normally if you specify a custom font for the body.font.family, the Symbol
font is automatically added to the font list in the font-family property of
the XSL-FO output. See:
http://www.sagehill.net/docbookxsl/SpecialChars.html#fontFamilyList
The internal parameter 'body.fontset' param handles that. Have you
customized 'body.fontset' to eliminate Symbol from it? And perhaps
customized the footnote.properties attribute-set to add it?

Subject: [docbook-apps] Problem with resolution of entities
Docbook 5, xsl 1.75.2, Oxygen 11.0 MacOS 10.4.11 Saxon 6.5.5 XEP 4.16 -
FO to PDF
I find that set theory symbols (∩ etc) resolve correctly in
footnotes to text in a <para> and in footnotes to text in a
<table><info><title>, but do not resolve in text (<para>) or text in
<table><tgroup>(<thead>|<tbody>)<row><entry>. I have tried both entity
names (∩ etc) and code points (∩ etc) - both react the same
way.
Looks like a bug, but any suggestions/help welcome.
The files are below, and the PDF output attached as test.pdf
