Subject: Re: [docbook-apps] Font problem - need 2 font files in Docbook
This is not a restriction of DocBook. Normally the font-family property in XSL-FO output is populated with a comma-separated list of fonts, not a single font. The 'body.fontset' internal parameter is used for body text, and it is set in fo/pagesetup.xsl by combining the body.font.family value and the symbol.font.family value, as described here: http://www.sagehill.net/docbookxsl/SpecialChars.html#fontFamilyList So this should already be working for you. Can you take a peek inside your FO output and see what the value of the font-family property on fo:root looks like? It should include your body font and symbol font in the list. If you are overriding the 'body.fontset' parameter, then you may not get a list. When XEP looks for a character, if it can't find one in the body font, it should then look in the next font in the list. That is, if font-selection-strategy="character-by-character" is also set (it is by default, in the 'root.properties' attribute set in param.xsl).
