Indeed.
If this is indeed "The standard way to do what you want", then the
standard needs to make it clear that the sequence of <space, combining
mark> or <NBSP, combining mark> has the properties which I want, i.e. it
has the width of the combining mark alone, and not the full width of a
space,
This is up to the implementation and the font, and is not something
that the Unicode Standard should mandate, IMO. This steps over the
bound of the plain text content.
...
Continuing to require that the Unicode Standard *must* specify
some inherent mechanism for indicating the display width of
combining character sequences clearly steps over the bounds
of what is required to represent plain text content.

Thank you, Ken. Well, you make it sound as if the problems are minimal,
and that version I can just about accept. But if Philippe is correct
about what he says about UAX#29 and UAX#14, there are some more serious
problems. It is certainly highly inappropriate for non-spacing
diacritics to be considered word boundaries. Philippe's quotations also
show that Unicode does concern itself with details of character
positioning and not just with plain text. Since Unicode does specify all
kinds of properties to do with spacing, breaking, word and sentence
boundaries, bidi behaviour etc etc, it is within the scope of Unicode
and indeed the responsibility of Unicode to define appropriate values of
all of these properties for spacing diacritics. I accept that some
things I have mentioned may have gone beyond this responsibility, so I
will withdraw those comments and continue to push only for appropriate
values of the properties which Unicode does define. And, if Philippe is
correct, many such properties are currently inappropriately defined, and
so either the text needs to be changed to correct these mistakes or a
new mechanism needs to be introduced.
