The right way in FO to switch hyphenation off is to switch hyphenation
off (hyphenate="false"). There is no semantics behind 200D in XSL FO,
and XEP just skips them. If you turn hyphenation off, then the words
will not be automatically hyphenated, and will only break on explicit
soft hyphens.

In fact, the stylesheets should switch hyphenation off on programlisting
and other verbatim items anyway.

I've looked at the code, and there is nothing special about font processing.
I've tested it, and it works; if the hyphenation character is not present in
the first font, it is taken from the second one.
