Re: [docbook-apps] Problem with resolution of entities

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?
