Thanks - I made a note in the Makefile - maybe I'll try that later.

I'm fairly sure the restrictions on an id attribute are the standard
restrictions on XML id attributes - i.e. they must follow the syntax of
NCName as specified in the XML specification(s).  (Slightly changed
over various XML versions, but never restricted to Ascii.)  I haven't
found an explicit statement to that effect in the DocBook specification,
but it seems implied that the syntax is an NCName.

ID nodes in HTML4 are restricted to ASCII.  I don't believe that that
restriction applies to XHTML.  In HTML5 the id attribute can be any
non-empty string without spaces:

http://dev.w3.org/html5/html4-differences/#changed-attributes
  The id global attribute is now allowed to have any value, as long as
  it is unique, is not the empty string, and does not contain space 
characters.
