[xep-support] Can specific code points be re-directed to a specific font family?

[DESEYNE Jacques]

I may be missing something, but if I want to render a portion of text such as:
 
<code>a &#x2246; b</code>
 
then I am not helped by producing things like:
 
<fo:inline font-family="Courier" font-size="10pt">a &#x2246; b</fo:inline>
 
as Unicode character 0x2246 (less than or equal to) has to be rendered using the Symbol font (I presume, as only this AFM has a
glyph 'lessequal'). 
 
Do I have to take additional measures such as:
 
<fo:inline font-family="Courier" font-size="10pt">a <fo:inline font-family="Symbol">&#x2246;</fo:inline> b</fo:inline>
 
(which means scanning your character data for specific code points)?
 
Or is there a way to impose Symbol (or ZapfDingbats etc.) for _specific_ code points, whatever the current font family happens to
be? The etc/fonts.xml file seems to offer no way to do this.
 
Best regards,
